ASEP A.CONCEPT Lecture: Design of Concrete Bridges

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

What: LEC-02: Design of RC Bridges

When: June 8, 2012

Time: 13:30-15:00

Where: La Breza Hotel, QC

Who: Resource Speaker – Alden Paul D. Balili

About the Lecture:

The National Structural Code of the Philippines (NSCP) 2011 Volume II Bridges, 3rd Edition is  updated to incorporate the latest bridge code provisions by the American Association of State Highway and Transportation Officials (AASHTO). This lecture intends to discuss the changes to key provisions in the Bridge code. Also, the concepts and principles behind the code provisions would also be discussed for a deeper understanding of the listener.

The lecture will be divided into two parts namely, (1) superstructure and the (2) substructure. The basic design steps for the superstructure will be discussed with emphasis on the allowable stress design checks for prestressed bridges, then the key code provisions and design concepts will be also be discussed but the emphasis will be on the seismic design for the substructure.

Keywords: Bridge Design, Seismic Analysis

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 A.CONCEPT Lecture: Seismic Detailing for Concrete Structures

Who: Resource Speaker – Christopher P. Tamayo, F. ASEP, PP

About the lecture:

SECTION 421 of the latest National Structural Code of the Philippines (NSCP 2010) is devoted to the provisions related to EARTHQUAKE-RESISTANT STRUCTURES.

The lecture is essentially a discussion of the salient provisions of Section 421, with the following objectives:

·    To briefly discuss the basic DETAILS of REINFORCEMENT required for structural integrity (Section 407 of the NSCP);

·      To review and integrate the relevant provisions of Section 421 of the NSCP which is sometimes referred to as Special Provisions of Detailing for a Seismic-resistant design;

·       To illustrate, through examples and practical applications, the differences i requirements between basic detailing and special seismic-detailing;

·     To bring to the awareness of design engineers, construction engineers, site inspectors, quality-assurance engineers, structural detailers, and the like of the importance of these provisions and help enhance their ability to spot probable deficiencies i n the details issued for construction so that appropriate adjustments may be carried out even before actual implementation.
