结合1栋高100m左右的框架-现浇空心楼板-核心筒结构,探讨了楼盖采用现浇空心大板体系的非矩形平面框架-核心筒结构的简化模型和计算方法。鉴于楼面厚板的抗侧作用,需设置一定的楼面暗框梁,暗框梁宽度取值可参考宽扁梁及板柱结构相关研究成果,且假定暗框梁仅承担自身重量及抵抗水平作用,不传递楼板竖向荷载;对比分析了简化计算模型的准确性。计算结果表明,简化模型在工程精度允许的范围内,满足工程设计习惯并且简单方便。
Combining with a frame about 100m high - cast-in-place hollow core floor and core tube structure, a simplified model and calculation method for the non-rectangular planar frame-core tube structure using the in-situ hollow slab system in the building floor are discussed. In view of the anti-side effect of the floor slab, a certain floor of the frame should be set, the width of the frame can refer to the research results of wide flat beam and slab structure, and assume that the frame only bear its own weight and resistance Horizontal effect, does not transfer the vertical load on the floor; comparative analysis of the accuracy of the simplified calculation model. The calculation results show that the simplified model is within the allowable range of engineering accuracy, meets the engineering design habit and is simple and convenient.
