Remarks Regarding FEMA 368 Seismic Analysis Guidelines
Author(s)
O. A. Mohamed
Abstract
The intent of this paper is to explore the recommendations of FEMA 368 on
seismic analysis of buildings from a structural engineers’ perspective. The
objectives are to: 1) illustrate the decision making process on the selection of a
seismic analysis method in FEMA 368, 2) present a clear sequence of steps that
will guide a structural engineer using FEMA 368 guidelines to determine the
appropriate analysis method by calculating the appropriate quantities as they are
needed, and 3) compare the response history analysis procedure to the equivalent
lateral force procedure permitted in the body of FEMA 368 guidelines.
Keywords: dynamic analysis, equivalent lateral force, response history analysis,
story drift, FEMA368.
1 Introduction
FEMA 368 is created with the sponsorship of the Federal Emergency
Management Agency (FEMA). The purpose of this document is to provide
guidance for the engineering community on the seismic resistant design of
structures. FEMA publishes updated recommendations on seismic analysis and
design every three years. It includes recommendations for structural and
nonstructural building components. In the year 2000, the National Institute of
Building Systems (NIBS) updated the Provisions for FEMA and the resulting
document is FEMA 368. The complete title of the document is NEHRP
Recommended Provisions for Seismic Regulations for New Buildings and Other
Structures. Presidential Executive Order 12699 mandates that all federal
buildings be constructed to mitigate seismic hazard and that NEHRP Provisions
are considered to be the suitable design standard [4]. Analysis and design
