Perforated steel plate concrete shear wall connecting beam provided with stud

Abstract

The invention discloses a perforated steel plate concrete shear wall connecting beam provided with a stud, and belongs to the field of building engineering. The connecting beam consists of a beam longitudinal rib 4, a connecting beam stirrup 5, connecting beam concrete 6, a steel plate 10, the stud 9 and steel plate perforations 11; and the perforated steel plate concrete shear wall connecting beam provided with the stud is a building or a structure in a form of the perforated steel plate concrete shear wall connecting beam provided with the stud. Because the steel plate adopted in the connecting beam is a planar member, the trouble that a vertical steel bar in a node zone wall is required to go around the flange of a steel beam, and construction is facilitated; because of packaging of the external concrete, the problems of internal and external instability on the plane of the steel plate and fire resistance are effectively solved; through the stud arranged on the steel plate, anchorage and stability of the steel plate and cooperation of the concrete and the steel plate can be ensured; and the connecting beam is suitable for high-rise and super high-rise buildings.

Description

technical field [0001] The invention relates to a building component, in particular to an open steel plate concrete shear wall connecting beam provided with studs. Background technique [0002] The shear wall is the main lateral force-resisting component of high-rise and super high-rise buildings. It is composed of horizontal reinforcement of the wall 1, longitudinal reinforcement of the wall 2, and poured concrete 3; composition, see Figure 1 to Figure 3 . Coupling beams are the joint force transmission hubs between shear walls, and are the key and weak parts of the structure. Because the span-to-height ratio of the coupling beams is generally small, the ductility of ordinary reinforced concrete coupling beams is poor, which is of great importance to the building structure. The anti-seismic performance is unfavorable. In recent years, due to the dual advantages of steel and concrete structures, the steel-concrete composite coupling beam has high bearing capacity and good ...

AI Technical Summary

Problems solved by technology

In the current engineering design, when the bearing capacity or ductility of the ordinary coupling beam is insufficient, the I-shaped steel concrete coupling beam is usually used, but the flange of the I-shaped steel will give the longitudinal tendons of the shear wall edge restraint members The layout brings inconvenience and causes construction difficulties, see Figure 5 , Image 6
