long span structure meaning in Chinese
大跨度结构
Examples
- Closed form solution for stationary random seismic response of long span structures considering wave passage effect
大跨度拱桥地震反应分析研究现状及进展 - The intensive growing of the chinese economy has imposed higher requirement for long span building construction not only for mediating the long span structure research and theoretical development problems but also to solve the important problems of the organization and design
中国经济的迅猛发展对建造大跨度建筑提出了更高的要求，除要解决大跨度结构的研究与开发方面的理论问题，还要着重解决施工组织及设计问题。 - 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。
