建筑结构设计理论和方法的基本出发点就是谋求安全可靠与经济合理的辩证统一。钢与混凝土联合梁结构充分发挥了材料和结构的特性,使钢梁与钢筋混凝土板二者之间彼此紧密联接成为一个整体而共同发挥作用,科学地把安全与经济结合起来,使结构设计条件和方法更符合实际需要。结构设计还要求型式简单,受力明确,内力分布简捷,尽可能做到结构型式和受力内容上的统一。联合结构要使钢梁与钢筋混凝土板联接成为一个整体,设置在钢梁翼缘上的联合件是这种结构的一个组成部分,它承受钢筋混凝土板与钢梁之间的全部剪力,以改进结构体系,增强结构的整体性能,因此联合件的设计与构造对联合结构设计的成败,至关重要。钢与混凝土联合梁结构在国外已获得了广泛应用,很多国家还颁布了有关设计规范,结合我国使用情况,尚需根据我国的材料、施工、安全度的表达,加以消化、整理才便于应用。为此,本期登载了关于钢与混凝土联合梁结构的一组文章,较系统地介绍了这种结构的设计,为推广联合梁创造必要条件,以便使这种结构在我国建筑中发挥更大的作用。
The basic starting point of architectural structure design theory and method is to seek the dialectical unity of safety, reliability and economy. The steel-concrete jointed beam structure gives full play to the characteristics of materials and structures, and the steel beams and reinforced concrete plates are closely connected with each other as a whole and function together, scientifically combining security with economy, and making structural design conditions And methods are more in line with actual needs. The structural design also requires simple types, clear forces, simple distribution of internal forces, and a unified structure and force content as much as possible. The joint structure is to connect the steel beam and the reinforced concrete slab into a whole. The joint piece arranged on the flange of the steel beam is an integral part of this structure. It bears all the shear forces between the reinforced concrete slab and the steel beam to improve the structure. The system enhances the overall performance of the structure. Therefore, the design and construction of the joint piece is crucial to the success or failure of the joint structural design. The steel-concrete joint beam structure has been widely used in foreign countries. Many countries have also issued relevant design specifications. Combined with our country’s usage, we still need to be digested and organized according to our country’s material, construction, and safety level to facilitate application. For this purpose, a set of articles on the joint structure of steel and concrete beams was published in this issue, and the design of this structure was systematically introduced. This created a necessary condition for the promotion of the joint beam in order to make this structure more effective in the construction of our country. The role.
