某空间管桁架拱门结构设计探讨

Design and discussion of a space pipe truss arch structure

对某空间管桁架拱门结构设计进行详细的论述。通过该结构探讨了不同蒙皮导荷方式、不同蒙皮自重取值和支座不均匀沉降对结构的影响。并提出以下针对管桁架结构设计的建议:重视风荷载体型系数的取值;重视蒙皮自重的取值和蒙皮导荷方式的选择;优先选用沉降较小的基础形式,从严控制管桁架沿跨度方向的差异沉降量。

Provide a detailed discussion on the design of a certain space pipe truss arch structure.Through this structure,the effects of different skin loading methods,different skin self weight values,and uneven settlement of supports on the structure were explored.And propose the following suggestions for the design of pipe truss structures:Pay attention to the value of wind load shape coefficient;Pay attention to the value of skin weight and the selection of skin load transfer methods;Priority should be given to using foundation forms with smaller settlement,and the differential settlement of the pipe truss along the span direction should be strictly controlled.
