Study on Seismic Behavior of Steel Frame with Different Brace Patterns

Abstract:

In order to analyze dynamic characteristics of steel frame with different pattern braces, three structures with brace of X, V and Λ patterns were designed utilizing STS of PKPM software respectively. Sizes of main members were provided through designed. Based on structural design, time history analysis under different earth waves were made by using ANSYS to investigate the effects exerted from different pattern braces on structural stiffness. Results showed that three different braces played an important role in strengthening structural stiffness. Braces with V and Λ patterns had approximate properties. The story drift ratio and the overall torsion of three different braces met the requirements regulated by Chinese design codes. Conclusions might be useful in practical engineering design during structural system selection.
