连续框架的英文
例句与用法
- Because of its advantages to resolve the lacking of stiffness of concrete beam , to nicely control the development of the cracks and deflection , and also because of its nice economy in use , prestressed concrete has been widely used in long span continuous frame
预应力技术由于能解决大跨度结构中混凝土梁的刚度问题，很好的控制结构的裂缝和挠度，具有良好的经济性能，因而广泛地应用于大跨度连续框架结构中。 - For example , the large friction loss of prestressed tendons , complex anchorage bearing joint , the problem of cracks in large area structure , axial compress of long span continuous beam under prestress . all those hinder its use in long span structure . until now days , the cognition about the behavior of such structure under loads is not enough for the realm of prestressed concrete of all the world
但是，预应力技术应用于大跨连续框架结构，在设计和施工中还存在一些缺点和不足，例如预应力筋的摩擦损失过大，节点锚固区设计和构造复杂、大面积结构的裂缝控制问题、大跨框架梁在预应力作用下的轴向缩短等，这些都是困扰大跨预应力混凝土框架结构应用的突出问题，特别是目前对于预应力混凝土超静定结构的受力性能，国内外预应力界的认识尚不够全面。
