Calculation methods for the ultimate stress and effective height of external prestressing tendons 体外预应力筋极限应力和有效高度计算方法
Relations between the fractal dimensions of tensile fractures and the tensile ultimate stresses for the grain composite material caco3 abs 拉伸断口表面分形维数与其拉伸强度极限的关系
Measures in force per unit area [ i . e . pounds per square inch ( psi ) ] the ultimate stress that can be withstood by a material in tension prior to failure 在出现问题前材料单位面积所能承受的极限拉力,例如:磅每平方英寸( psi ) 。
An important step in structure design is the calculation of the ultimate flexural strength of external prestressed concrete beams , which needs to calculate the ultimate stress increment of external tendons first 结构设计的一个重要环节就是极限承载力计算,而计算体外预应力混凝土梁的极限承载力就必须求得梁在破坏时的体外筋应力增量。
At last , the effect of the steel yield strenth , the yield - to - ultimate stress ratio , the shape and size of the access hole is researched . in conclusion , the finite - elenent model and the program adoped in this paper can well similate the response of beam - to - cloumn connections uder cyclic load 本文所建立的模型及采用的程序能够很好的模拟、研究在循环荷载作用下刚性梁柱连接的反应,为进一步研究刚性钢框架梁柱连接的抗震性能打下了基础。
