Seismic Analysis of Woodframe Structures. II: Model Implementation and Verification Bryan Folz, M.ASCE,1 and Andre Filiatrault, M.ASCE2 Abstract: This is the second of two companion papers on the seismic analysis of woodframe structures. In Part I, a simple numerical . d model was formulated to predict the dynamic characteristics, quasistatic pushover, and seismic response of woodframe buildings. This e v r e numerical model has been incorporated into the computer program SAWS seismic analysis of woodframe structures. Here in Part II, s e r s attention turns to implementation and verification of the SAWS model. To this end, the predictive capabilities of the SAWS program are t h g compared with experimental results obtained from recent shake table tests performed on a full-scale two-story woodframe house under the i r l l CUREE-Caltech Woodframe Project. It is shown that the SAWS computer program provides reasonably accurate estimates of the dynamic a ; y characteristics, quasistatic pushover, and seismic response of the test structure. Furthermore, the SAWS program requires a minimum l n o e amount of data input and provides a fast computational turnaround time in which to analyze a given structure. As a result, this simple s u l numerical may be a useful structural analysis tool for practicing engineers and researchers involved in the seismic design and/or analysis a n of woodframe structures. o s r e p r DOI: 10.1061/ASCE0733130:91361 o F .
