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

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

What: LEC-04: Seismic Detailing for Concrete Structures

When: June 8, 2012

Time: 15:00-16:30 PM

Where: La Breza Hotel, QC

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.

About the lecturer:

Christopher P.T. Tamayo, F.ASEP, PP, is the Proprietor and Managing Consultant of TandeM Engineering Consultancy. He serves as a Consultant to projects in the Philippines as well as overseas projects, e.g. Hong Kong, Macau, United Arab Emirates, Republic of Marshall Islands, and Guam. He has over twenty-three (23) years of experience in Structural Engineering Design of Multi-story and Multi-purpose Building Developments in reinforced concrete and structural steel using American/Philippine and Hong Kong/British Design Standards.

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
