Problems solved by technology

Although this method can finally meet the construction needs, it is time-sensitive and consumes more manpower and mechanical resources on site.
Especially in emergencies, it is impossible to evaluate the stress state of the steel structure grid in time, which affects the preparation of on-site emergency measures

Abstract

The invention discloses a BIM-based steel structure net rack hydraulic lifting time-varying finite element analysis method. The BIM-based steel structure net rack hydraulic lifting time-varying finite element analysis method comprises the steps that 1, a real-time steel structure hydraulic lifting BIM three-dimensional model is imported into finite element software, model properties are set according to a construction drawing, and a time-varying finite element model is established. 2, finite element numerical simulation is verified by utilizing actually measured stress-strain detection results to generate a time-varying construction process mechanics cloud picture; 3, the time-varying construction process mechanics cloud picture is fedback to the BIM three-dimensional model, a stress state of steel structure rack hydraulic lifting at a corresponding stage is displayed; 4, analysis and early warning are conducted on the zone which is not in a stable state in the model to facilitate timely adjustment in a field. The project department can make corresponding emergency measures in time if major security hidden dangers occur. The BIM-based steel structure net rack hydraulic lifting time-varying finite element analysis method has the advantage of achieving timely monitoring and early warning of the stress situation of a steel structure net rack.

Description

technical field [0001] The invention relates to the technical field of BIM technology informatization construction, in particular to a method for implementing time-varying finite element construction mechanics simulation based on a BIM platform for safety early warning. Background technique [0002] BIM is an indispensable platform for the design, construction and maintenance information management of civil engineering, water conservancy engineering and other industries. But so far, it cannot be connected with the construction site, and cannot directly create benefits for construction management. In this invention, BIM technology is directly applied to the construction management of steel structure grid hydraulic lifting, as an early warning technology for its safety lifting. [0003] The traditional hydraulic lifting monitoring scheme uses small lifting, manual measurement and review of the lifting balance state, and gradually adjusts the spatial posture of the steel struc...
