檩条在风吸力作用下的稳定计算

Stability Calculation of Purlin under Wind Uplift Loading

对蒙皮支撑简支 Z型檩条在风吸力作用下的性能进行了试验研究 ,并分别按门式刚架规程和澳洲冷弯型钢结构规范计算了檩条在风吸力作用下的稳定承载力。

Behavior of simply supported,diaphragm braced Z shaped purlins, was tested under wind uplift loading. The stability bearing capacity of purlin was calculated by two formulas of criterion and compared to the tested result. Some suggestions on the design of purlin are proposed.
