Abstract

The invention belongs to the technical field of building structure testing and discloses a method for testing the structural mechanical properties of a polygonal building film. The system comprises: acurvature detecting module, a hardness detecting module, a weight detecting module, a central control module, an environment simulation module, a test data storage module, a cloud service module anda display module. The invention also discloses a method for testing the mechanical properties of a polygonal building film structure. The environment simulation module can simulate the real factors ofthe natural environment in a test, greatly improve the reliability of the test result and enrich the test modes. The cloud service module can use a cloud server to concentrate the big data computingresources and to analyze the test performance data so that the data processing speed is greatly improved, the test cycle is shortened and the test efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of building structure testing, and in particular relates to a method for testing the mechanical properties of polygonal building membrane structures. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Membrane structure is a new type of large-span space structure developed in recent decades. It consists of fabric (membrane material) with excellent performance through supporting members (such as rigid beams, columns, flexible cables), or adding air in the membrane. It is a form of spatial structure in which the pressure is combined in a certain way and appropriate initial pretension is applied to form a spatial structure shape with a certain rigidity, thereby bearing a certain external load. Its history can be traced back to ancient times when people used the fibers of trees and hides to build tents. Membrane structure is a brand-new f...

AI Technical Summary

Problems solved by technology

[0006] Existing methods for testing the mechanical properties of building membrane structures are single, and the test effect is poor; at the same time, the calculation and analysis speed of the test data is slow, and the test cycle is long, which affects the test efficiency

[0007] In hardness testing, the accuracy of data obtained by existing testing methods is poor, and the convergence speed of existing algorithms is not ideal, and it is easy to fall into a local optimal solution, resulting in low data calculation efficiency and poor accuracy
