Influence Analysis of Layout of Braces on Structural Dynamic Properties of Large Space Multi-storey Buildings
Taking a six-storey steel frame construction as the research object, parameters under study are the horizontal space of braces nodes and the layout of vertical braces.Based on the analysis of the structural period, layer displacement and angles of storey drift, research on the influence of layout of braces on structural dynamic properties of large space buildings is conducted.The results show that when column spacing is larger, braces-setting contributes to significantly improve the structures lateral stiffness and reduce the section size of columns, and that the section size of braces can be reduced by shortening the horizontal space of braces nodes.Braces should be set between the columns as full as possible.It is better to set the vertical braces positioned in the center instead of on the side between the columns.The lateral stiffness is higher when braces are set concentratedly than dispersedly.Its more economical to set the inclined braces uniformly.
