摘要
提出采用剪力释放方法解决钢筋混凝土剪力墙结构的连梁超限,即在连梁中点人为设定部分固定竖向弹簧刚度,对杆件内力进行释放,使连梁的最大包络剪力设计值满足剪压比要求。计算结果符合预期,该方法不受连梁截面宽度和高度的影响,可以毫无困难地进行动力分析,具有很强的可操作性,并提出了相应的设计对策。
The shear release method was presented for solving the out-of-code problems for coupling beam in RC shear wall structure. The part-fixed hook rigid was artificially established at the middle of the eoupling beam to release the beam internal forces and make the maximum envelope shear value satisfy shear-compress ratio requirement. Calculating results achieved the desired results. The method was unaffected by width and height of coupling beam seetion, and the dynamic analysis could be readily oro^ressed with stron~ maneuverability. The relevant design measures were oresented.
