钢结构模块单元双梁等效研究

Equivalent research on double beams of steel structure module unit

模块化建筑是指将一个房间或者三维空间结构作为模块单元,在现场通过堆叠、组装形成整体结构建筑。模块单元是模块化建筑的基本组成,针对模块化建筑下模块单元顶板梁和上模块单元底板梁组成的双梁结构,为了简化计算按抗弯刚度等效原则,结合ABAQUS有限元软件将双梁结构等效成单梁模型,并分析底板梁高度对等效单梁截面刚度的影响。

Modular building refers to a room or three-dimensional space structure as a modular unit,which is stacked and assembled on site to form an overall structural building.Modular unit is the basic component of modular building.For the double beam structure composed of the top beam of the module unit and the bottom beam of the upper module unit in the modular building,in order to simplify the calculation,according to the principle of equivalent bending stiffness,the double beam structure is equivalent to a single beam model by ABAQUS finite element software,The influence of bottom beam height on equivalent single beam section stiffness is analyzed.
