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.

Ulpiano
P. Ignacio, Jr., F. ASEP, is a Professor
of Civil Engineering at the University of the Philippines Diliman. He is also a
PICE accredited Structural Engineer. He has been teaching civil engineering
courses at the undergraduate and graduate level at UP Diliman for the past 34
years. He also served as Chairman of the
Department of Civil Engineering, Director of the UP Building Research Service,
Vice Chancellor for Administration of UP Diliman, and Assistant Vice President
for Development of the UP System. As a Structural Engineer he has designed
residential, commercial and industrial structures for local and international
clients. He graduated with a BSCE, cum
laude, from UP Diliman in 1978. He obtained his Master of Science (CE) from
the Ohio State University in 1981. His specialization is in structural dynamics,
earthquake engineering and structural design and analysis of buildings.
