Seismic Behavior Analysis on the Steel Cold-Formed in Modular House

Abstract

The cold-formed thin-walled steel has such advantages as light-weight , good seismic capability and is suitable for reconstruction in seismic disastrous area. Nonlinear analysis by software ANSYS on the performances of static and dynamic of a 2 -story building has been done. The analysis reveals that: (1) under the conditions of participation in the earthquake, the top lateral value of structural is large and the maximum is 9.985 mm, but all lateral displacement values standard requirement. (2) Based on the analysis under three kinds of seismic waves, the corner roofing of second independent room has much larger displacement values than others, torsion has been happened on structure. (3) Under the seismic wave, the maximum value is 2.47 which happened on the 400cm/s2 of Taft wave; structure has obviously response under Taft wave。
