It puts forward that when skating from a low speed to a high speed,in the relationship between step frequency and step speed,way of dynamic support follows way of fixed-point support,but in the relations of step length and step speed,it is opposite.

It puts forward that when skating from a low speed to a high speed,in the relationship between step frequency and step speed,way of dynamic support follows way of fixed-point support,but in the relations of step length and step speed,it is opposite.

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.
