A risk assessment model based on concrete stress strain

Abstract

The invention relates to the technical field of building structure stress monitoring, in particular to a concrete stress-strain-based risk assessment model, which acquires stress parameters of a structure, inputs them into a structure model of a risk assessment subsystem, and outputs the stress parameters from the risk assessment subsystem The initial risk point after strain in the structure model; obtain the construction condition information of the structure, compare it with the preset construction conditions of the structure model to obtain the update information, use the update information to update and correct the structure model, and then update and correct the structure by updating and correcting the structure. After the model, the risk assessment subsystem outputs the revised risk point again according to the stress parameter, and makes the difference between the position of the initial risk point and the position of the revised risk point to obtain the difference. Risk assessment is performed on the structure model before the correction, otherwise it is judged that the update and correction are invalid, and the risk assessment is performed on the updated and corrected structure model. The invention improves the accuracy of structural risk assessment.

Description

technical field [0001] The invention relates to the technical field of building structure stress monitoring, in particular to a risk assessment model based on concrete stress and strain. Background technique [0002] Structures such as slopes, tunnels, bridges and dams formed during construction are mainly composed of concrete. The high mechanical strength of concrete ensures the durability of structures such as slopes, tunnels, bridges and dams. , When the concrete is affected by the external environment during use, such as temperature, pressure or tension, the internal structure will generate stress and strain in order to adapt to the external environment, resulting in the internal structure of slopes, tunnels, bridges and dams. There are risks such as cracks or gaps. If the risk of these structures is not assessed, the entire structure may be damaged due to small internal risk points. [0003] Aiming at the risk of structures such as slopes, tunnels, bridges and dams, th...
