ASEP Continuing Education Lecture: Design of Structural Steel Members using LRFD

ASEP Continuing Education Summit 2012 invites you to a lecture on:

What: CEL-04: Design of Structural Steel Members using LRFD

When: June 9, 2012

Time: 11:00 – 12:30

Where: La Breza Hotel, QC

Who: Resource Speaker – Alfredo B. Juinio, Jr., F.ASEP

About the Lecture:

                                                     

The main objective of structural engineering design is to produce a safe and economical structure that will serve its intended purpose.  Safety in this context is primarily provided by ensuring that the structure’s strength is sufficient to resist the maximum load actions that may act during the life of the structure.  However, the determination of strength of the structure and values of the loads are at best only estimates.  Because of uncertainties in the strength and load actions, design specifications generally prescribe a generally accepted design methodology to ensure that the probability of the strength being less than the load actions is small.

Historically, the Working Stress Design Method (WSD) was the most prevalent.  In the past few decades, this has been supplanted by the Load and Resistance Factor Design (LRFD) Method.   In the current National Code of the Philippines (NSCP 2010 Volume I, Buildings, Towers and other Vertical Structures, 6^th Edition), the provisions of the 2005 specifications of the American Institute of Steel Construction, Inc (AISC) were adopted for Chapter 5 on Structural Steel.  These specifications prescribe the use of the LRFD and the Allowable Strength Design (ASD) Methods.

The lecture will cover discussions on uncertainties in the determination of strengths and load actions, margin of safety, load factors and load combinations, strength reduction factors, and the concept of limit states.  Limit states are conditions beyond which the structure or structural component ceases to fulfill its intended function.  Aside from the use of partial factors for loads and strength, as opposed to a single factor of safety in the WSD, the adoption of the limit state design philosophy into the LRFD is probably the most important improvement of the LRFD.  A qualitative overview of the limit states and codal provisions for structural steel members in tension, compression and flexure shall also be presented.

ASEP Continuing Education Lecture: Effects of Unchartered Faults of the NSCP 2010

ASEP Continuing Education Summit 2012 invites you to a lecture on:

What: CEL-08, Part A: Effects of Unchartered Faults of the NSCP 2010

When: June 9, 2012

Time: 16:00-16:40

Where: La Breza Hotel, QC

Who: Resource Speaker – Engr. Carlos M. Villaraza, F.ASEP

About the Lecture:

Earthquake Engineering is both an art and a science that is in continuous evolution. As new data from research and observations of structural performance during actual earthquakes are gathered, existing parameter may either be reinforced or revised. The Philippines has an extensive earthquake data that need to be classified to be of use to the current knowledge in earthquake engineering. These historical non-instrumental data extends from 1589 until 1901 when instrumental records became available. The first Building Code to require seismic analysis was in 1966. Since then, country’s National Structural Code of the Philippines (NSCP) has been updated 8 times to conform to the present state of the art in earthquake resistance design.

Until the 5^th Edition of the National Structural Code of the Philippines, it has adopted in its entirety the Uniform Building Code of the United States. Lately, more studies were conducted regarding the seismicity of the country. In the absence of Strong Ground Motion data, simulations were made to come up with its own seismic acceleration map applicable to the country. Although it is still cross-referenced to the International Building Code of the United States, experiences from recent earthquake events in Japan last 11 March 2011 and the February 2011 event in New Zealand has been studied for correlation purposes.

About the Lecturer:

Carlos M. Villaraza is a Structural-Earthquake Engineering Consultant. He has over thirty five years of extensive experience in structural engineering design, seismic design parameter studies and seismic risk analyses. He has been involved in the review of the earthquake provisions of the National Structural Code of the Philippines since 1987 and Chairman of the NSCP 2010 General Requirements and Loads & Actions, a member of the APEC Informal Network on earthquake provisions for the Harmonization of Building Codes in the APEC Region and the review of ISO provisions covering lateral loads and general loading conditions.

A graduate of B.S. Civil Engineering from the University of Santo Tomas – Manila (1976), he received his Post Graduate Diploma in Earthquake from the International Institute for Seismology and Earthquake Engineering in Japan (1986).

ASEP Continuing Education Lecture: Geophysical Methods in Civil Engineering – Practical Applications

ASEP Continuing Education Summit 2012 invites you to a lecture on:

What: CEL-06: Geophysical Methods in Civil Engineering – Practical Applications

When: June 9, 2012

Time: 13:30 – 15:00

Where: La Breza Hotel, QC

Who: Resource Speaker – Emilio M. Morales, CE, MSCE, F.PICE. F.ASCE, F.ASEP

About the Lecture:

Geophysical methods are generally noninvasive or nondestructive methods long used in the construction industry for investigation of the subsurface. Principally, these are used for the detection of geologic anomalies such as cavities and voids, detection of buried pipes and other utilities, detection of water bearing aquifers for well development, exploitation of quarries and in determining soil stratification or layering. In addition, the methods provide a means for verifying as constructed pavement thicknesses in a continuous unbroken image of the pavement structural configuration or determining rebar embedment and layout non-destructively.

The use of geophysical methods confers advantages as they generally speed up the process of investigation, provide continuous streams of information not otherwise available in discrete sampling or invasive procedures and give advance information on what to expect for a given locality before a more detailed and costly soil exploration is even planned. Thus geophysical methods are a force multiplier for the engineer and allow the user to identify potential problem areas or target areas even before the start of a detailed Soil Exploration program.

Geophysical methods are not a replacement to a detailed soil exploration program; rather they augment these programs to yield more meaningful and area extensive but more intensive information at the fraction of the time and cost.

The Paper discusses three general methods which have been employed by the authors in various projects. Case histories are discussed to highlight successful deployment of these methods in the Construction Industry.

ASEP A.CONCEPT Lecture: Development of Practical Tools for Vulnerability and Safety Evaluation of CHB Houses in the Philippines

ASEP Summit 2012 invites you to an A.CONCEPT lecture on:

What: PLE-01: Development of Practical Tools for Vulnerability and Safety Evaluation of CHB Houses in the Philippines

When: June 8, 2012

Time: 9:30-10:30 AM

Where: La Breza Hotel, QC

Who: Resource Speaker – Hiroshi Imai, PhD.

About the Lecture/Abstract:

In the past earthquakes, the loss of life was most commonly caused by collapsed buildings constructed by using masonry. These collapsed buildings were not constructed to be earthquake resistant, hence called “Non-Engineered Construction”, which are ironically, widely constructed in seismic prone areas. For the housing situation in the Philippines, most of the non-engineered houses are CHB masonry structures. Therefore, it is necessary to investigate the seismic performance of these existing CHB houses for disaster mitigation.

The Shaking Table Test was conducted on February 2011 at the National Research Institute for Earth Science and Disaster Prevention (NIED), Tsukuba Japan, to investigate some typical houses in the Philippines. The house specimens (3600 x 3600 x 2600mm) are of two types, Model A is an “Engineered” model complying with the National Structural Code of the Philippines 2010, 6^th Edition (NSCP 2010), and Model B is a “Non-Engineered” model  which is a typical house constructed in Philippines. Through the Shaking Table Test, the vulnerable points of the CHB structures were figured out.  It was particularly shown that in the “Non-Engineered” model, the end gable CHB wall and mortar joints of masonry units were vulnerable to damage, and some of the factors affecting damage were the quality of the CHB grout (mortar used to fill the CHB’s hollow part), and strength of CHB unit itself, etc.

The first step for disaster reduction is to understand the disaster risk. In order for earthquake disaster reduction to be successful, it is critical that the stakeholders such as government officers, masons and contractors, community leaders, and house owners should understand the earthquake risk, which includes the estimated damage of their house, community and city. To promote earthquake disaster mitigation, the stakeholders must understand the earthquake risk as their own problems, and must take actions as their own task with the technical advice from the professionals.

These practical tools (Seismic Diagnosis) aim to raise awareness among the stakeholders, by a simple evaluation of the safety/vulnerability of houses as an education tool.

As the purpose is to raise awareness but not to provide accurate estimate, the programs of the tools may give rough results, omitting some minor factors.

The “Practical Tools for Vulnerability and Safety Evaluation o f CHB houses of the Philippines” are the following:

STEP1 - Practical tools 1: Let’s check your house.

The “score” indicating the safety/vulnerability of the house is evaluated by homeowner by answering ten (10) questions concerning the shape of the floor, wall openings, type of foundation, type of roof, age of the house, etc.  Thus, the homeowner is made to understand which components of the house are important for determining its safety/vulnerability.

STEP2 - Practical tools 2:  Software to evaluate safety/vulnerability of CHB houses

The focus of this practical tool is the CHB masonry structure, which aims for homeowners, with the assistance of a civil engineer, to understand and evaluate the safety/vulnerability of their house and help them acquire a relevant knowledge for retrofitting the CHB masonry structure.

This tool, using a computer simulation program with a visual and user-friendly interface, is still in its development stage.  It is based upon field data, experimental data and the NSCP 2010.   To show the reasons for the safety/vulnerability of the house, and how to improve its safety against earthquakes, the program user will be made to input data about ground conditions, foundation, floor plan, allocation of walls, roofing, reinforcement, age, etc.  The program output includes the scoring of the house, the reasons for its safety/ vulnerability, and advice to strengthen the house, if necessary.

This presentation is based upon the on-going study, “Development of Practical Tools for the Vulnerability and Safety Evaluation of CHB houses of the Philippines”

ASEP A.CONCEPT Lecture: Pushover Analysis of RC Buildings

ASEP Summit 2012 invites you to an A.CONCEPT lecture on:

What: LEC-03: Pushover Analysis of RC Buildings

When: June 8, 2012

Time: 15:00-16:30 PM

Where: La Breza Hotel, QC

Who: Resource Speaker – Ulpiano P. Ignacio, Jr., F. ASEP

About the Lecture:

Pushover Analysis is an incremental nonlinear static analysis used to determine the force-displacement relationship for a structure or structural element. Conventional analysis procedures use linear elastic methods. However, large earthquakes can cause large deformations causing inelastic and nonlinear behavior. Therefore, the use of linear elastic methods, although greatly simplifying the engineer’s work, may lead to erroneous conclusions. On the other hand, using nonlinear dynamic analysis using time history loading, considered as an “exact” procedure, may be very complicated and prohibitive in terms of modeling and computer resources. Hence, a nonlinear static analysis, also called pushover analysis, is a very good compromise for most applications. This lecture intends to introduce the concept of pushover analysis applied to building structures.

At the end of the presentation, the participants are expected  to:

•  know the concept of  pushover analysis and its resulting pushover curve;
•  know the overall procedure in performing a pushover analysis;
•  know the uses of a pushover analysis, e.g. as a tool in the retrofit of existing buildings, development of fragility and vulnerability curves, and in conducting a Performance Based Seismic Design of structures.

Keywords: Pushover analysis, Nonlinear Static Procedure, Seismic Analysis
