This paper introduces the design points and construction techniques of cast-in-place reinforced concrete truss slabs in steel structure buildings through a large-scale engineering example, which can serve as a reference for similar projects. The museum has one basement level and five above-ground levels, with a total building area of 66,927 square meters and a building height of 44.75 meters. The main structure adopts an internal steel pipe reinforced concrete shear wall-steel truss cantilevered suspension structure. Because this project adopts a large-span suspended structure system, the research results of the floor vibration reduction system of the Department of...

Regarding the question of how to arrange the reinforcement in steel decking, we will explain it in detail here. We will address the reinforcement calculation for steel decking in two parts: the top reinforcement (including negative moment reinforcement) and the bottom load-bearing reinforcement. The top reinforcement, also called distribution reinforcement or temperature reinforcement, mainly serves to resist the tensile stress generated in the direction perpendicular to the slab span by seasonal temperature changes and concrete shrinkage. Generally, the diameter of the reinforcement should not be less than 6mm, and the spacing should not exceed 250mm. The...

Due to the steel truss steel deck significantly reducing on-site steel bar binding work, accelerating construction progress, and enhancing construction safety guarantees, it has a very wide application in factory and civil housing construction. To ensure construction safety, we need to carry out construction correctly in the following order and methods. Let's take a look! Steel Truss Steel Deck Installation Sequence 1)Construction sequence A. Plan construction sequence: The laying of each floor's steel truss steel deck should preferably be done starting from the construction drawing's initial position in one direction, and the edge and corner parts should be handled...
