摘要
对无梁楼盖采用单重三角级数及双重三角级数的公式,求得板内的弯矩分布。根据已知的边界条件以及板柱协调工作原理,建立无梁楼盖挠度函数和内力的弹性分析解,找出了零弯矩分布规律,提出了板、柱体系在竖向荷载作用下的简化实用的计算方法———板格法。这种方法设计合理,内力分布符合实际,改变了传统的跨中板带,柱上板带的划分计算无梁楼盖的方法,有利于实际工程的应用并对实际工程具有参考价值。
This article uses single trigonometric series and double trigonometric series formulas to obtain the bending moment distribution for the slab in slab-column system. Aeeording to the known condition of boundary and the principle of coordination work, the paper biults the formulation of slab-column system flexure function and internal force analysis in elasticity and identifies the distribution of the zero moment curve. A new slab-column system simplified and practical designed method is proposed under the vertiele unifrom load ＂Slab-grid method＂. This method is logical and realistic in the internal foree distribution. And it changes the traditional calculated method which divides the middle slab and the slab above the column in slab-column system. Also the method is beneficial to application and directive significance to actual engineering.
