Abstract

The invention belongs to the technical field of cable glass curtain wall construction, and specifically provides a method for tracking internal force and deformation during cable tensioning construction. S01: Calculate the initial strain required to meet the pre-applied force through an inverse iteration method, and then calculate the tension The actual internal force and actual displacement corresponding to the initial strain of the cable, the inverse iteration method includes the improved tension compensation iteration method; S02: After the initial strain value obtained by the previous iteration, the initial strain value is used as the initial value of the next cycle calculation. Strain value; S03: When the cycle reaches k times, if the difference between the actual internal force of the cable and the pre-applied force is less than the preset value, the cycle ends, and the stress value obtained by each calculation above is recorded corresponding to each tension stage. The actual internal force of the cable, where k is greater than 1. According to the target cable force of the cable at each stage, the corresponding internal force and deformation of the cable are calculated, which provides theoretical data and reference for construction, and improves the safety and reliability of the construction of the cable glass curtain wall.

Description

technical field [0001] The invention belongs to the technical field of cable glass curtain wall construction, and particularly relates to a method for tracking internal force and deformation during cable tensioning construction. Background technique [0002] In the process of glass curtain wall tension control, the formation and size of the rigidity of the zipper itself depends entirely on the size of the prestress applied to each cable member, the tension sequence, and the prestress relaxation state (redistribution of the internal force caused by the tension sequence). ), supplementary tension, etc. When designing the cable structure, only the geometric configuration, stress, deformation state and bearing requirements of each cable in the design state are often given. As for how to form the target configuration, stress and deformation state, it is unknown, which needs to be carried out before construction. Sophisticated computer simulation analysis and iterative calculatio...
