Abstract

The invention discloses a deformation and stress synchronous control method in a roof unloading process. The method is characterized by comprising the following steps of 1, finite element analysis; 2,determining the initial sensor layout nodes; 3, determining an optimal section layout position of the sensor; 4, acquiring the deformation and stress real-time data of a steel structure; 5, updatingthe finite element model in real time; 6, predicting the deformation and stress data at the next unloading stage; 7, updating the unloading scheme, updating the unloading scheme according to the prediction result in the step 6, and timely taking a reinforcing measure at the position of a component with the stress and deformation close to thresholds, so that the deformation and stress synchronous control method has higher precision compared with a traditional method, is simple, easy to operate and is 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 usually 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 str...
