Abstract

The invention relates to a building self-weight load evaluation method based on reliable indexes, belongs to the field of building structure detection and identification, and solves the problem of self-weight load evaluation. The method comprises the steps of analyzing self-weight load probability distribution of a building in a design stage, calculating a variable coefficient suitable for a load design expected condition, and establishing a relational expression between the variable coefficient and a subitem coefficient; and determining a self-weight load subitem coefficient of the design expected condition based on a reliable index. The method is used for evaluating the safety of the existing building structure. According to the method, the smooth implementation of sampling detection of the single existing building can be ensured, and the evaluation of the self-weight load of the single existing building is realized.

Description

technical field [0001] The invention relates to the field of detection and appraisal of building structures, in particular to a method for evaluating building self-weight loads based on reliable indexes. Background technique [0002] "Unified Standards for Reliability Design of Building Structures" GB 50068-2018, etc., in accordance with the provisions of the international standard ISO 2394 and the European code EN 1990, divide the load into four types: permanent design conditions, transient design conditions, accidental design conditions and seismic design conditions. Among them, the permanent design condition is equivalent to the load duration of the permanent design condition such as "Unified Standard for Reliability Design of Building Structures" GB 50068-2018. However, the connotation of the expected design situation is: for the partial coefficient of the self-weight load, it is only the partial coefficient expected in the design stage of the building structure engineer...
