Design method of a sectional type reinforced concrete coupling beam with dual functions of bearing and energy dissipation

Abstract

The invention relates to a design method of a sectional type reinforced concrete coupling beam with dual functions of load bearing and energy dissipation. The sectional type connecting beam is composed of an energy consumption section and a bearing section, the bearing section is higher than the energy consumption section, and the height difference ranges from 250 mm to 400 mm. The bearing sectioncan be used for independently bearing the load of a floor beam according to the state of the cantilever beam, cannot yield under the earthquake fortification effect and cannot obviously reduce the bearing capacity under the rare earthquake effect, and the bearing function of the connecting beam under the large earthquake effect is achieved. The energy dissipation section allows yield and even serious damage to occur in a rare earthquake, and therefore the energy dissipation function of the connecting beam under the rare earthquake effect is achieved. The sectional type connecting beam not only can solve the problem that a floor system main beam is not suitable for being placed on a connecting beam of a core tube or an inner tube in practical engineering, but also has the dual functions ofbearing and energy dissipation, and is convenient to construct, material-saving, convenient to install and good in economical efficiency.

Description

technical field [0001] The patent of the present invention relates to the field of structural design in civil engineering, in particular to a design method of a segmented reinforced concrete coupling beam with dual functions of load bearing and energy consumption. Background technique [0002] Coupling beam is an important connecting component between shear walls in high-rise building structures. As the main energy-consuming component, it is the first to enter the yield energy dissipation under the action of frequent earthquakes and rare earthquakes, which can greatly reduce the damage caused by earthquakes. loss. Article 6.7.3 of "Code for Seismic Design of Buildings" (GB 50011-2010) stipulates that the floor beam should not be supported on the inner tube connecting beam. Article 7.1.5 of "Technical Regulations for Concrete Structures of High-rise Buildings" (JGJ 3-2010) stipulates that floor beams should not be supported on the coupling beams of shear walls or core tubes;...

AI Technical Summary

Problems solved by technology

However, when the floor beams are arranged as oblique beams, the material loss is large, the construction is inconvenient, and it is not conducive to room division and equipment layout. Therefore, in actual engineering, there are often problems in which the connecting beams support the floor beams.
