Steel reinforced concrete composite beam and bending resistance design method of steel reinforced concrete composite beam
The invention relates to the technical field of buildings, in particular to a steel reinforced concrete composite beam and a bending resistance design method thereof, the steel reinforced concrete composite beam comprises a prefabricated main body and a pouring main body, and the prefabricated main body comprises a T-shaped steel part, a reinforcement cage part and a prefabricated concrete part; the T-shaped steel part comprises a web plate, a flange and a plurality of connecting parts, and the connecting parts are arranged at the connecting ends, away from the flange, of the web plate; one part of the web and one part of the reinforcement cage are embedded in the prefabricated concrete part; the precast concrete part and the pouring main body are made of ultra-high performance concrete, the pouring main body is connected with the precast concrete part, and the other part of the reinforcement cage, the connecting part and the connecting end of the web are all embedded in the pouring main body. According to the steel reinforced concrete composite beam and the bending resistance design method of the steel reinforced concrete composite beam, the compactness of concrete pouring is improved, the thickness of a protective layer of the section steel is reduced, the tensile strength of the section steel is fully exerted, and the durability of the steel reinforced concrete composite beam is improved.
本申请涉及建筑技术领域，尤其是涉及一种型钢混凝土组合梁及型钢混凝土组合梁抗弯设计方法，型钢混凝土组合梁预制主体和浇筑主体，预制主体包括T型钢部、钢筋笼部和预制混凝土部；T型钢部包括腹板、翼缘和多个连接部分，连接部分设置于腹板的远离翼缘的连接端；腹板和钢筋笼的一部分埋设于预制混凝土部；预制混凝土部和浇筑主体为超高性能混凝土，浇筑主体与预制混凝土部连接，且钢筋笼的另一部分、连接部分和所述腹板的连接端均埋设用于浇筑主体内。根据本申请提供的型钢混凝土组合梁及型钢混凝土组合梁抗弯设计方法，提高混凝土浇筑的密实度，降低型钢的保护层厚度，使型钢的抗拉强度充分发挥，提高型钢混凝土组合梁的耐久性能。
