Abstract

A method for synchronous control of deformation and stress during roof unloading, characterized in that it includes the following steps: Step 1, finite element analysis; Step 2, determining the initial sensor layout node; Step 3, determining the optimal section layout position of the sensor; 4. Obtain real-time data of steel structure deformation and stress; step 5, update the finite element model in real time; step 6, predict the deformation and stress data of the next unloading stage; step 7, update the unloading plan: update the unloading plan according to the prediction results of step 6 , and timely reinforcement measures are taken at the component where the stress and deformation are close to the threshold, which has higher precision than the traditional method; the deformation and stress synchronization control method in the present invention is simple, easy to operate, and low in cost.

Description

technical field [0001] The invention relates to the technical field of roof unloading control, in particular to a method for synchronously controlling deformation and stress during roof unloading. Background technique [0002] In large-scale building structures such as gymnasiums and factories, steel structure roofs are widely used due to their light weight and ability to withstand loads such as suspended stands. Due to the large size and complex component design of this type of structure, it is often impossible to hoist it in place at one time. It is often assembled with the help of temporary supports. After the structure is formed as a whole, the load on the temporary supports is gradually removed and removed. During the unloading process of the temporary support, the force of the structure and the temporary support will be gradually transferred, and the internal force will be redistributed, which will directly affect the initial internal force and deformation of the struc...
