Frame structure model correction method based on simplified model

Abstract

The invention provides a frame structure model correction method based on a simplified model. The method aims to achieve equal interlayer shear force of a simplified model and a frame structure. A frame structure novel simplified model capable of considering the influence of the beam-column joint corner is established. The invention provides an identification method for identifying simplified model parameters by adopting a monitored frame structure floor horizontal acceleration response, the simplified model parameters are converted into a state space, and a structure dynamic response prediction model of the frame structure under the action of dynamic loads such as earthquakes and wind is established based on the simplified model. The model can accurately predict the real response of the frame structure under the load effect. The method solves the problem that an accurate prediction frame structure dynamic response model is difficult to establish in a traditional frame structure modelcorrection method adopting a shear model.

Description

technical field [0001] The invention belongs to the technical field of architecture, in particular to a frame structure model correction method based on a simplified model. Background technique [0002] Frame structure is a common form of high-rise building structure. However, due to multiple complex coupling effects such as material aging, environmental erosion, and long-term load effects, most of the active frame structures are damaged to varying degrees and their bearing capacity is reduced. For this reason, scholars from all over the world have successively carried out the research on the revision of architectural structural models, trying to establish a model that can reflect the real structural dynamic response behavior, and use the model to predict structural response and structural safety assessment. In order to facilitate analysis and calculation, scholars at home and abroad often use simplified models such as shear models to simulate the dynamic response of comple...

Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problem that the corrected model cannot accurately reflect the actual dynamic response of the frame structure due to the large model error of the traditional shear model when the frame structure model is corrected, and proposes a frame structure model correction based on a simplified model method
