4) multi-story and multi-span
多层多跨
1.
In the design of the multi-story and multi-span prestressed concrete frame structures(PCFS),tendons of frame beams usually were designed by crack resistance capacity and it was hard to avoid "strong beam-weak column" and "strong element-weak joint" around inner beam-column joints.
在设计多层多跨预应力混凝土框架结构时,一般按抗裂度控制条件计算预应力筋后再按允许的预应力度确定普通钢筋的数量,则节点抗剪强度不足和“强梁弱柱”难以避免;如果满足梁的截面相对受压区高度的结构位移延性规定,则梁的抗裂度不易满足。

补充资料:多苯基多亚甲基多异氰酸酯
多苯基多亚甲基多异氰酸酯,简称PAPI,或称粗MDI,浅黄色至褐色粘稠液体.有刺激性气味。相对密度(20℃/20 ℃)1.2,燃点218℃。PAPI实际上是由50%MDI与50%官能度大于2以上的多异氰酸酯组成的混合物。升温时能发生自聚作用。溶于氯苯、邻二氯苯、甲苯等。PAPI的活性低,蒸气压低,只是TDI的百分之一,故毒性很低。
