在工厂设计中,在满足生产使用要求的同时,应尽可能节药建筑材料,特别是钢材和水泥等重要材料。这是设计人员应该遵守的原则。根据这样的原则,我们在一些厂房设计中采用了混合结构。由于混合结构是用两种不同的材料(砖和钢筋混凝土)作成,而这两种材料的物理力学性能相差很大,如何充分发挥这两种材料的性能,使其断面的承载能力更接近于实际的工作情况,并使其很好地共同工作,这是一个值得研究的问题。我们知道,砖砌体的受压性能尚好,但受弯性能很差;而钢筋混凝土的两种性能都很好。砖砌体与钢筋混凝土同时用在承重结构中,当受到弯矩(特别是水 In the design of the factory, while satisfying the requirements for production use, it is necessary to save as much as possible construction materials, especially important materials such as steel and cement. This is the principle that designers should follow. Based on this principle, we have adopted a hybrid structure in some plant designs. Because the hybrid structure is made of two different materials (brick and reinforced concrete), and the physical and mechanical properties of these two materials are quite different, how can we give full play to the properties of these two materials and make the bearing capacity of the cross section closer to that of The actual work situation, and make it work well together, this is a question worth studying. We know that brickwork has good compressive properties, but its bending performance is poor; while reinforced concrete has good properties. Brickwork and reinforced concrete are used simultaneously in load-bearing structures when subjected to bending moments (especially water
