Abstract
In recent years, several researchers have confirmed that the steel panel shear wall (SPSW) can be a viable seismic force resisting system for building structures. Although the SPSW can cost-effectively satisfy the lateral stiffness, strength and ductility requirements for seismic buildings, research on large scale SPSW structures are rather limited. The purposes of this combined experimental and analytical investigation on the seismic responses of SPSW structures include: 1) investigate the seismic performance of a full scale two-story steel panel shear wall structure, 2) investigate the capacity design criteria of the boundary beam and column elements surrounding the steel panels, 3) investigate the effectiveness and seismic design of the lateral restrainers for the SPSW, 4) incorporating the PISA3D into the networked substructure pseudo-dynamic tests of the 2-story SPSW structure, 5) investigate the seismic performance of the RBS connections in the SPSW specimen, 6) investigate the effect of the concrete slab in preventing the buckling of the girder when large inter-story drifts and severe buckling of the SPSW occurred, 7) validate the TensionOnly material implemented for the PISA3D in simulating the responses of the SPSW structure.
Measuring eight meters tall and four meters wide, the 2-story SPSW structure is considered to be the world largest ever tested. The thickness of SS400 grade steel plate for first story wall is 3mm and for second story is 2mm. All the boundary beam and column elements are A572 GR 50 steel. Preliminary research results indicate that the post-buckling strength of several one-story SPSW specimens can be satisfactorily predicted by using the strip model and the tension-only material implemented for the PISA3D program. In addition, it is found that the direction of the tension field action can be more accurately predicted if the flexural responses of the boundary beam and column elements are considered. It is found from the analysis that the flexural demand imposed on the top boundary beam can be satisfactorily predicted by the superposition of vertical load effects on the fix-ended beam and horizontal load effects on the moment resisting frame. It is found that the bending moment distribution computed in this manner can be applied for the capacity design of the boundary beam element. The precise flexural demand imposed on the column requires further investigation. The full scale 2-story SPSW specimen has been constructed since April 2005, and is scheduled for testing in August, 2005.
