| 摘 要： | 钢筋混凝土双向密肋楼盖由于具有结构高度小、经济、美观、自重轻和变形小等特点,在实际工程中的应用已日趋广泛。但是,目前对这种结构开裂后的变形计算方法,以及破坏时的机构形态和极限荷载的研究尚少见报导。为此,本文作者做了一个四边简支钢筋混凝土双向密肋楼盖的大比例模型试验,根据试验结果,建立了这种结构的破坏机构,推导了其极限荷载公式,给出了楼盖从开裂至破坏的变形计算方法。

| Abstract: | The reinforced concrete waffle floor slab, which is provided with distinguishing features of low structural height, economical, artistic, light self-weight and small deflection, has been applied progressive widely to practical projects. But up till now, there is still short of the informations for study the method of calculating structural deflection ofter cracking as well as the mechanism of failure and ultimate limit loads of such structure. Hence, a vast scale model of four sides simply supported reinforced concrete waffle floor slab has been tested by the authors of the paper, then, based on the test results of above mentioned model that the mechanism of failure for such structure was set up, its ultimate loading formula was derived and the deflections from cracking to failure of such floor slab were given. |
