对在建筑中作为门窗的钢板剪力墙的大矩形开孔加固的非线性性能进行研究。对一些开孔和未开孔的钢板剪力墙进行数值分析:1)用分析结果对开孔的钢板剪力墙的性能进行描述;2)研究开孔处局部边界梁结构的开孔特性、大小和开孔处任意边的填充板厚度所带来的影响;3)调查开孔所带来的系统强度和刚度的改变。结果显示,根据AISC20《钢结构设计规范》来解决开孔处上、下梁的设计并不完善。对局部边界梁结构使用略厚或略薄的内填充板将会改变整体的屈服顺序。显而易见,尽管不同开孔所需的不同局部边界梁结构的大小会对其有一定的影响,开孔加固的类型﹑位置﹑形状并不会影响整体强度。在不同的钢板剪力墙中使用开孔加固可以增加其极限强度和刚度,而略微减小延性比。
The nonlinear behavior of large rectangular openings reinforced with steel plate shear walls as windows and doors in buildings was studied. Numerical analysis of some perforated and non-perforated steel plate shear walls: 1) Describe the performance of the perforated steel plate shear wall with the analysis results; 2) Study the perforated characteristics of the local boundary beam structure at the perforation, Size and thickness of the filler plate at any edge of the opening; 3) Investigate the change in system strength and stiffness caused by the opening. The results show that according to AISC20 “Steel Structure Design Code” to solve the hole at the upper and lower beam design is not perfect. Using a slightly thicker or thinner inner filler plate for the local boundary beam structure will change the overall yield order. Obviously, although the size of different local boundary beam structures required for different openings will have an impact on them, the type, location and shape of the hole reinforcement will not affect the overall strength. The use of hole reinforcement in different steel shear walls increases the ultimate strength and stiffness while slightly reducing the ductility ratio.
