Abstract
Using ABAQUS6.5 the time-history of the followed models is analyed: the model of common central braced frame,and that of central braced frame using BRB with low yield point steel under big earthquake,it is found that using BRB with low yield point steel,can not only solve the problem of buckling,but also all decrease displacement response.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
