Snow load photovoltaic light-steel agricultural greenhouse static test method and operation procedure

Abstract

A snow load photovoltaic light-steel agricultural greenhouse static test method and an operation procedure relate to the technical field of static tests. The method comprises the following steps of analyzing the structural strength of a photovoltaic light-steel agricultural greenhouse by ANSYS WORKBENCH software, and determining a stress and strain typical area; attaching a strain gauge (strain rosette) and a displacement meter to a selected area; arranging a loading tool, and determining a load applying mode, a load applying position, a load applying strength, and a load applying direction according to design load and snow load requirements in a 'steel structure design specification'; and connecting a stress strain tester. The method can quickly and accurately measure whether key components in the 'steel structure design specification' satisfy the yield strength and the tensile strength, and the overall deformation of the key components; effectively saves analysis time and improves analysis efficiency under the same operating conditions, and has the ability to carefully check and quantify the details of the connection and part of the greenhouse.

Description

technical field [0001] The invention relates to the technical field of static test, in particular to a static test method and operation process of a snow-loaded photovoltaic light steel spring and autumn shed. Background technique [0002] Photovoltaic light steel spring and autumn shed is a new photovoltaic agricultural greenhouse developed according to market demand. It has the advantages of standardized large-scale production and modular assembly. However, the structure of this type of greenhouse is more complicated than traditional greenhouses, and its static test is also relatively complicated. The design of photovoltaic light steel spring and autumn sheds must comply with the "Code for Design of Steel Structures". For structural strength under working conditions, engineers and technicians at this stage usually use PKPM software to check, and then design and finalize the design. During the analysis process, local details such as the connection between the rods of the gr...
