Research on Simplified Model for Steel Plate Wall with Slits

As a kind of lateral force resistant component for high-rise buildings of steel structures,steel plate walls with slits have been applied in the actual structures.But it is hard to get such systems generalized for its difficulty of modeling and seeking convergence results.In this paper a simplified cross brace model with three-line axial force-deformation curve is presented to simulate the behavior of steel plate walls with slits.Numerical simulation is conducted on six specimens,showing good accuracy of the proposed model in test analysis.This cross brace model is used in a five story frame for pushover calculation,comparing with a single brace model's results in terms of basic period,failure mode and the location of plastic hinges.And the distribution of bending moments in the beam is more reasonable if the cross brace model is used.
