内嵌墙板钢框架空间效应研究

RESEARCH ON THE SPATIAL EFFECT OF STEEL FRAME WITH ENCLOSURE WALLS

为了解围护墙板对平面钢框架受力性能的影响及带墙板钢框架空间受力性能,运用ANSYS有限元软件首先建立强轴及弱轴带墙板平面框架,分析墙板对空框架的影响。在此基础上,建立单跨两层空间框架模型,分析在不同墙板布置形式下带墙板钢框架的空间受力性能。结果表明:纵向框架带有墙板时能够使横向空框架承载力提高20%以上。工程设计中可通过在框架每层设置弹簧单元调节空框架的层间刚度来考虑墙板的作用,通过对6层框架结构的分析验证了该方法是可行的。

In order to know the effect of embedded wallboard on the mechanical behavior of steel frame and the spatial mechanical behavior of steel frame with wallboard, ANSYS was used to establish the strong axis and weak axis plane framework with wallboard to analyze the effect of the wallboard on empty frame. On this basis, a single span two-layer space frame model was established to analyze the spatial mechanical behavior of steel frame with different disposal of wallboard. The result shows that the longitudinal framework with wallboard can make the bearing capacity of horizontal empty framework increase by more than 20%. It can be designed the steel frame with walls by setting the spring unit in each story of the empty frame. This way was verified by analyzing the six-story frame structure.
