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.

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.

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

ASEP Plenary Lecture: Prestressed Concrete Design & Construction: A State of the Art Report

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

What: PLE-02: Prestressed Concrete Design & Construction: A State of the Art Report

When: June 8, 2012

Time: 11:00-12:00 AM

Where: La Breza Hotel, QC

Who: Resource Speaker – Brian Lim (VSL-Intrafor, HK)

About the lecture:


Post-tensioning has been one of the most significant developments in the 20^th Century. It has contributed greatly to the economical construction of bridges, through the use of innovative construction methods such as cantilever construction, incremental launching and in particular through precast segmental construction methods in bridges. In buildings, prestressed precast and in-situ post-tensioning are the preferred construction method in many countries for many types of building structures such as offices, shopping centres, convention centres, warehouses, car parks, hotels and resorts. Recent developments in national codes, construction material and emphasis on sustainable construction, have led to a significant departure in the way we design and construct prestressed concrete structures. In this paper, a state of the art prestressed concrete design and construction of buildings, bridges and special structures will be examined.


Keywords: State of the art, prestressed, concrete, design, construction, bridges, buildings.
