Secondly, the least length of pretensioned prestressed concrete slab is defined to make the full use of steel strand strength and avoid flexural crack occurs within the development length.
其次为使构件破坏时充分发挥预应力钢绞线的强度,防止弯曲裂缝出现在延伸长度之内,提出了先张预应力混凝土板在均布荷载作用下的最小板长。
We get the CFRC can increase the flexural rigidity, reduce the size and number of the crack, increase the bearing capacity.
可以得出采用碳纤维布加固的钢筋混凝土梁能有效提高抗弯刚度,减小裂缝尺寸及数量,提高承载力。
Based on the experiments of the 12 SRC flexural members, the stiffness, crack width and ultimate bending strength of the SRC beams are analysed.
本文以12个型钢钢筋混凝土(以下简称SRC)梁受弯试验为基础,对SRC梁的刚度、裂缝宽度和受弯承载力进行试验研究和理论分析。
