混凝土叠合构件短期刚度计算方法研究
|
摘要
混凝土叠合构件(梁、板)是装配式建筑主要使用的水平受力构件。钢筋混凝土叠合构件、预应力混凝土叠合构件在一次受力、二次受力作用下呈现不同的受力、变形特点。本文阐述了一次、二次受力叠合构件的受力、变形机理,系统总结了叠合构件弯曲变形计算关键参数短期刚度的8种计算方法;论述了这8种方法的基本原理、适用范围,讨论了各方法典型的计算公式以及各国规范公式的推导要点;探讨了叠合构件短期刚度计算方法需要进一步研究的问题。
Concrete composite beams and slabs are main members under horizontal loads in prefabricated building.There are different mechanical and deformation performance of concrete composite members according to reinforced concrete and prestressed concrete in one stage of loading and two stages of loading upon the serviceability limit state.Firstly, special mechanical and deformation performance of the concrete composite members one stage of loading and two stages of loading were introduced. Secondly, eight kinds of calculating methods for short-term stiffness under bending were summarized which was the important parameter for deformation of concrete composite members. The basic principle and scope of application of eight calculating methods were described in which the major points of the deviation of several typical formulas and the current code formulas were emphasized. Finally, it was discussed the issues of calculating methods for short-term stiffness of concrete composite members, which needs further research.
