文摘:本文分析了弯道水流的基本特性，阐述了充分淹没在水下的导流屏特性和由此引起的河床剪应力之间的关系，给出了弯段河道导流屏护岸原理及设计方法。 - As soon as the normal section cracks , the crack firstly appears in the flexural region . at this moment , the load - deflection curve has a turning point . with the increase of the load , the rigidity of the beam decreases compared with that before cracking because of the development of cracks in flexural region , and the formation and development of diagonal cracks toward the loading point , the load - deflection curve is basically linear till the beam fails
正截面开裂前，荷载挠度曲线基本为线性，截面刚度较大；正截面开裂时，裂缝先在纯弯段出现，荷载挠度曲线出现转折点，随着荷载的增加，纯弯段正裂缝的发展以及剪跨段斜裂缝的产生并向梁的受压区加荷点发展，使梁的刚度较截面开裂前减少，荷载挠度曲线也基本为线性直到梁破坏。 - The study in the paper starts with beam distortions , and it treats the plastic deformation area as pure bending sect , rest of the beam as rigid bodies . according to different shapes of the external tendons , it divides into three structural forms familiar in projects , that is the beams with no deviator , with a deviator and with two deviators , and studies the relation between the deformation of the external prestressing tendons and that of the beams , and derives the formulas of the ultimate stress increment of external tendons . in the formulas , the ultimate angle corresponding to half of the plastic deformation area is considered as a variable parameter
本文首先从梁极限状态下的变形入手,将塑性铰区看作纯弯段,将塑性铰以外的区域看作刚体,按照体外预应力筋的形状不同,分工程中最常见的三种体外结构形式,即无转向块的直线型体外筋混凝土梁、具有一个转向块的单折线型梁和具有两个转向块的双折线型梁,研究体外预应力筋变形和梁体的变形间的关系,推导出以极限状态下塑性铰区之半对应的转角为参数的计算体外预应力混凝土简支梁以及连续梁的体外筋应力增量计算公式,并进一步求得梁的极限承载力。
