26 Jul FEMA Improvement of Nonlinear Static Seismic Analysis Procedures iii. Forward. One of the primary goals of the Department of. Homeland Security's Federal Emergency Manage- ment Agency (FEMA) and the National Earthquake. Hazards Reduction Program (NEHRP) is to encour- age design and. project will culminate with the publication of FEMA Improvement of Nonlinear Static. Seismic Analysis Procedures. This paper provides a preview of the key conclusions of the work. The focus is on anticipated recommendations to improve inelastic analysis procedures as currently documented in FEMA  and ATC. In last decades, through further development of computer technology in civil engineering, the more complex seismic analysis became possible and accuracy of the analysis is increased. ATC 40, FEMA , , and recently are the most commonly used resources for seismic analysis procedures enduring with.
20 Dec In recent documents on Nonlinear Static Procedures (NSPs), FEMA (), a modified damping ratio of the replacement oscillator was proposed by introducing the ductility of the soil-structure system obtained from pushover analysis. In this paper, the damping defined in FEMA to include the. 19 Dec Full-Text Paper (PDF): On the FEMA regulations for soil-structure interaction.

Abstract: Nonlinear static procedures (NSPs) presented in the FEMA document are evaluated for nondegrading three- to nine-story reinforced concrete moment-resisting frame systems. Evaluations are based on peak single- degree-of-freedom displacement, peak roof, and interstory drifts estimations. A total of 78 soil. Replacing the entire soil-structure system with a fixed base oscillator to consider the effect of soil-structure interaction (SSI) is a common analysis method in seismic design. This technique has. 15 Feb The Purpose of the Seminar is to present newly developed guidance for improved application of (1) the. Coefficient Method, as detailed in the FEMA Prestandard and Commentary for the Seismic Reha- bilitation of Buildings, and ( 2) the Capacity Spectrum. Method, as detailed in the ATC Report.
