Static elastoplastic analysis of the composite shear wall of the grid -tube- type double steel plate wall with infilled concrete

Abstract

In this paper, the new idea is proposed on the composite shear wall of the grid -tube- type double steel plate wall with infilled concrete, the model test was carried out, and combined with practical engineering, for instance, a 18th floor high-rise building pushover static elastoplastic analysis is discussed. Research shows that the hysteresis curve of the new composite shear wall is relatively full, and has good seismic performance with high bearing capacity, high ductility and high energy consumption capacity. Under the action of rare earthquakes, the interlayer displacement is small on structural system with concrete filled steel tubular column and he composite shear wall of the grid -tube- type double steel plate wall with infilled concrete, and the new composite shear wall is distributed more base shear. Research shows that structural system on composite shear wall with grid -tube- type double steel plate wall with infilled concrete has good seismic performance.
