Method for checking calculation of arc wall and inclined wall reinforcing bars

Abstract

The invention provides a method for checking calculation of arc wall and inclined wall reinforcing bars. It is assumed that walls are provided with section steel bars according to a stress result, the steel bars in the walls only bear uniaxial stress, concrete tensile strength is omitted, and the steel bars in the walls are in a yielding critical point; it is assumed that tensile stress in sections is completely borne by the steel bars arranged in the direction and the steel bars yield just now, stress borne by concrete is shearing stress of the walls and normal stress in which steel bar tension is removed, and if the stress can be borne, it shows that the wall reinforcing bars can meet the bearing force requirements; if not, the sections or the reinforcing bars need to be adjusted, and calculation is conducted again until the wall reinforcing bars meet the bearing force requirements. Whether the arc wall and inclined wall section reinforcing bars can meet the section bearing force requirements or not can be rechecked according to the practical engineering situation. The design status mainly depending on an estimation means in the prior art is changed, the arc wall and inclined wall reinforcing bars are quantified and rechecked, and the structure construction and design of practical engineering can be directly guided.

Description

technical field [0001] The invention relates to a method for checking and calculating the reinforcement of an arc wall and an inclined wall, which belongs to the transformation technology of the method for checking and calculating the reinforcement of an arc and an inclined wall. Background technique [0002] In "Technical Regulations for Concrete Structures of High-Rise Buildings" (JBJ3-2010), the applicable formulas for the bearing capacity of shear wall front sections are rectangular, T-shaped and I-shaped. The reinforcement of the wall is solved according to the internal force of the section. The premise of this calculation method is that the section of the wall meets the assumption of a plane section. For the inclined wall of the arc wall, both the plane and the elevation belong to the unconventional section, and the common assumption of the plane section is no longer applicable. At this time, the calculation formula of the code is still relied on to solve the component...

Problems solved by technology

In view of the fact that the existing codes do not provide relevant methods for the design and calculation of the bearing capacity of such complexly deformed walls, it is mainly to estimate the reinforcement of the wall according to the magnitude of the cross-sectional stress, but it is difficult to determine whether the estimated wall reinforcement can meet the bearing capacity.
