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。
The structure is analyzed by software 3D3S and MIDAS. The steel amount of whole structure can be reduced by adjusting the initial pretensioned value of cables.
采用3D3S和MIDAS软件对结构进行分析,通过控制拉索的初始预应力取值,降低整个结构用钢量。
