为研究沿海地区集装箱组合房屋墙板的抗风性能和抗剪性能,分别进行抗风性能试验和抗剪性能试验。通过将300 km/h风速下的风荷载按照能量等效原则转换为自由落体冲击荷载,对集装箱组合房屋墙板的抗风性能进行试验研究。结果表明:随着试件尺寸的增加,抗风性能逐渐减弱;对相同尺寸的无焊接波纹板钢框架试件和有焊接波纹板钢框架试件进行水平荷载作用下的抗剪性能对比试验。结果表明:波纹板对框架的侧向支撑作用明显,可有效提高构件的平面内抗弯刚度和承载能力。当构件尺寸大于某一数值时,随着尺寸的增大,其抗剪承载力减小。
In order to study the wind-resistance and shear-resistance of container composite wall panels in coastal areas, the wind-resistance and shear-resistance tests were carried out respectively. The wind resistance of container composite wallboard was tested by converting the wind load at wind speed of 300 km / h into free-fall impact load according to the energy equivalence principle. The results show that the wind resistance decreases gradually with the increase of the specimen size. The comparison test of the shear resistance under the horizontal load of the steel frame specimen with the same size without welding and the corrugated steel frame with welding. The results show that the corrugated board has obvious lateral support to the frame, which can effectively improve the in-plane flexural rigidity and load carrying capacity of the component. When the size of the component is larger than a certain value, the shear capacity decreases with the increase of the size.
