Seismic screening, evaluation, and rehabilitation design of two existing wood-framed structures are performed using FEMA 154, FEMA 356, ASCE/SEI 31, and the 1997 UBC. FEMA 154 screening demonstrates the importance of examining construction drawings. Plans revealed a structural deficiency, but screening alone indicated no further evaluation is needed. Demand-to-capacity ratios for shear walls an...

The objective of this investigation is to evaluate the FEMA-356 Nonlinear Static Procedure (NSP) and a recently developed Modal Pushover Analysis (MPA) procedure using recorded motions of four buildings that were damaged during the 1994 Northridge earthquake. For this purpose, the motions at non-instrumented floors are “derived” from the motions at instrumented floors by using cubic spline inte...

This paper comprehensively evaluates the Modal Pushover Analysis (MPA) procedure against the ‘‘exact’’ nonlinear response history analysis (RHA) and investigates the accuracy of seismic demands determined by pushover analysis using FEMA-356 force distributions; the MPA procedure in this paper contains several improvements over the original version presented in Chopra and Goel (2002). Seismic de...

pushover analysis is a simplified nonlinear analysis technique that can be used to estimate the dynamic demands imposed on a structure under earthquake excitations. one of the first steps taken in this approximate solution is to assess the maximum roof displacement, known as target displacement, using the base shear versus roof displacement diagram. that could be done by the so-called dynamic p...

This paper compares the target displacement estimate from four current nonlinear static procedures—FEMA-356 CM, ASCE­ 41 CM, ATC-40 CSM, and FEMA-440 CSM—with the value derived from recorded motions of five strongly shaken reinforced concrete buildings.This comparison provides useful insight into two important questions: (1) how much does the target displacement vary among the four nonlinear st...

The role of higher-“mode” pushover analyses in seismic analysis of buildings is examined in this paper. It is demonstrated that the higher-“mode” pushover curves reveal plastic hinge mechanisms that are not detected by the first-“mode” or other FEMA-356 force distributions, but these purely local mechanisms are not likely to develop during realistic ground motions in an otherwise regular buildi...

Special Plate Shear Wall (SPSW) merupakan struktur rangka yang terdiri dari pelat baja vertikal (infill plate) sebagai dinding pengisi tersambung dengan balok dan kolom, berfungsi untuk menahan beban seismik. Penelitian ini bertujuan mengetahui tingkat kinerja gedung SPSW terhadap variasi penampang kolom menggunakan metode analisis pushover bantuan software ETABS. Struktur klinik 6 lantai, tota...
