Abstract

The invention discloses a method for improving the safety performance of a space truss structure, belongs to the technical field of building structure reinforcement, and solves the problems that in the prior art, whether a truss has enough safety or not cannot be determined, and the distribution condition of the stress state of a rod piece cannot be visually displayed. The method comprises the following steps: S1, acquiring parameters of a space truss structure; s2, inputting the parameters obtained in the step S1; s3, enabling the processor to read the data in the data memory to establish a net rack finite element model; s4, applying design load and constraint to the finite element model through a data recorder; s5, sending the finite element model packaged by the processor to a display terminal through a data sender, and displaying the stress condition of the rod piece graphically; and S6, reinforcing the rod piece according to the stress condition of the rod piece. The method is suitable for improving the safety performance of the space truss structure.

Description

technical field [0001] The invention belongs to the technical field of building structure reinforcement, in particular to a method for improving the safety performance of a space grid structure. Background technique [0002] In the series of renovation projects, there are many grid projects that have certain problems in the construction and supervision process, and there are practical problems such as lack of design drawings. Therefore, after the on-site inspection of the project is completed, it is necessary to carry out checking and analysis on the actual grid structure to clarify the actual bearing capacity of the current structure, so as to determine whether the grid structure has sufficient safety in the subsequent use process, so as to Ensure that the structure will not collapse causing serious personal injury or property damage. At present, most of the analysis software related to the grid structure focuses on the design aspect, and the grid analysis method specially...
