RESEARCH ON CONCEPTUAL PROBLEMS OF DESIGN OF BEAM STRING STRUCTURE
-
摘要: 张弦梁结构以其跨度大且用钢少的优势引起了诸多关注。对该结构在设计中的几个概念问题进行了探讨,包括如何看待下弦拉索的转角摩阻、确定撑杆间距的方法、下弦索工作应力限值以及拱梁截面等。Abstract: The beam string structure has been concerned due to its long-span capacity and economization of steel. The conceptual problems of the design of the structure are researched, which include how to regard the corner friction of bottom chord stay, the method of determining the space between stay bars, the limit value of working stress of bottom chord stay and the section of arched beam etc.
