When the steel frames are installed with Buckling-Restrained Braces(BRBs), whose aseismic performance will be improved, but the function of energy dissipation and vibration control is influenced by the layout principle of BRBs.

This paper states the actuality,arrangement principle and mode of thruway service district.

This paper researched the influence of bracing kinds on lateral stiffness of multi-storey and high-rise braced steel-frames Through calculating the biggest sidesway of top-storey of the steel-frame braced by different types and layouts of bracing,.

The paper introduces briefly the comparison analysis for the two vertical support layout structures in "the post comprehensive building in Hohhot city" and the continuous joint design for some new steel components and concrete components,and provides some structure design experience for some high rise steel structure.

The paper uses the finite element analysis software ANSYS,by analyzing and comparing the response of the high-rise building to some typical brace layout schemes under the effect of rare earthquake,discusses the seismic behavior of the brace layout mode to braced steel frame,so as to make it apply better in the construction structure\'s practice.
