摘要
针对钢构早拆模板体系这一新型模板施工技术,结合现有规范,通过有限元分析,分析了在不同混凝土拆模强度、不同跨度和不同板厚条件下的钢筋混凝土板抗冲切承载力、抗弯承载力、裂缝和挠度情况,提出相应的技术建议。
The early disassemble steel formwork system is a new construction technique. The punching shear strength, flexural capacity, crack width and deflection, in different formwork disassemble strength of concrete, different spans of slabs and different heights of slabs conditions, were calculated by means of finite element analysis. Some useful suggestions were put forward on the basis of the above results. The theoretical analysis and test in this article can guide the application of early disassemble steel formwork system in construction practices.
