| 摘 要： | 钢-混凝土组合板近年来在建筑及桥梁结构领域逐渐受到关注,但目前关于组合板弹性稳定性能方面的研究较少,尤其是局部屈曲性能。剪力连接件(栓钉)的最大间距是防止钢板局部屈曲先于屈服的最关键因素,也是保证组合板中钢板与混凝土板协同工作的前提。采用有限元计算方法,通过模型参数分析,研究四边简支钢-混凝土组合板在纯剪切作用下发生局部屈曲的特征,建立具有典型边界条件单块钢板计算模型来模拟组合板中栓钉包围钢板局部屈曲特性,从而推导出四边简支组合板栓钉连接最大间距的计算公式,计算结果偏于安全。

| Abstract: | The steel-concrete composite slab is becoming popular in the fields of building and bridge structures.Nevertheless,at present little study on the foundational performance of elastic stability of steel-concrete composite slab for all practical purposes is available,especially on its local buckling behavior.The maximal spacing of shear connectors(such as studs) is the most important factor to prevent the steel plate from local buckling before yielding,and it also makes steel plate and concrete slab behave as ... |
