Design method of reinforced concrete basement exterior wall structure without horizontal floor slab support

Abstract

The invention relates to a design method of a reinforced concrete basement exterior wall structure without a horizontal floor support. An overhanging edge beam which does not affect building use is additionally arranged at the elevation position of a basement floor slab for a reinforced concrete basement outer wall without a horizontal floor slab support, brackets serving as supports of the overhanging edge beam and concrete floor beams which extend inwards along the brackets and are connected with the basement floor slab are designed at the two ends of the overhanging edge beam, and the height of the brackets is not smaller than that of the overhanging edge beam; through analysis and calculation of the method, the overhanging edge beam is designed to be a horizontal fulcrum of the basement exterior wall without the floor support, so that the design of the basement exterior wall without the horizontal floor support is converted into the same design method of the basement exterior wall with the horizontal floor support, and the method is clear in concept, simple in calculation model and calculation method, convenient for manual calculation and high in practicability. And the method is highly practical and can be easily mastered by vast structural designers. Practice proves that the design method is simple, convenient, safe and reliable.

Description

technical field [0001] The invention relates to the field of building structures, in particular to the architectural structure design of a reinforced concrete basement, and relates to a method for designing a reinforced concrete basement exterior wall structure without horizontal floor support. Background technique [0002] In the structural design of reinforced concrete basements, it is often encountered in architectural design that large openings are required to be opened on the adjacent floors of the basement exterior wall, such as openings for equipment hoisting and lighting patios, etc., see figure 1 Schematically, 1 in the figure is the reinforced concrete basement exterior wall supported by the horizontal floor slab, and 2 is the basement floor slab. At this time, the internal force of the basement exterior wall without horizontal floor support is significantly different from that of the basement exterior wall with floor support. The thickness of the exterior wall nee...

AI Technical Summary

Problems solved by technology

At this time, the internal force of the basement exterior wall without horizontal floor support is significantly different from that of the basement exterior wall with floor support. The thickness of the exterior wall needs to be increased. The structural design often needs to be analyzed by complex structural finite element programs. Some structural designers are not familiar with complex The use of structural finite element programs makes the design cumbersome and difficult, and requires a safe, reliable, and convenient practical design method that conforms to the principles of mechanical calculations
