Embodiment Construction

[0055] Such as Figure 9 As shown, the present invention provides a method for improving the anti-typhoon ability of buildings. The technical solution of the present invention will be described in detail below by taking the damage caused by the super typhoon "Meranti" to the Jimei Campus of Xiamen University of Technology as an example.

[0056] 1. Design of Data Acquisition Scheme

[0057] 1.1 Research area and scheme design

[0058] The research area is located in the vehicle detection and test center experimental base between Building 9 and Building 10 of Jinggong Park, Jimei Campus, Xiamen University of Technology. The experimental base is a group of steel structure buildings with complex geometric shapes and rich details. To meet the requirements of refined information extraction of damaged houses, it is necessary to obtain high-precision laser point cloud data of the damaged houses. First, conduct a site survey. Since the house has just been damaged by a super typhoon...

Abstract

The invention discloses a method for improving a building's anti-typhoon capability, comprising the following steps: step 1, constructing a two-dimensional line drawing and a three-dimensional model of a typhoon-damaged building; the detailed steps of step 1 are: a, obtaining the disaster-damaged building The laser point cloud data of objects; b, registration and splicing of point cloud data to obtain 2D line drawing; c, solid modeling of 2D line drawing combined with point cloud data to obtain a 3D model of the building Step 2, calculate the damage area according to the two-dimensional line drawing of the building, judge the damage type of the building structure according to the three-dimensional model, and adopt different design schemes for different structures of the building according to the damage type. This method can construct a three-dimensional model of a typhoon-damaged building, and provide theoretical guidance for the typhoon-proof structure of the building based on the three-dimensional model.

Description

technical field [0001] The invention relates to a method for designing a building structure in typhoon weather, in particular to a method for improving the building's anti-typhoon capability. Background technique [0002] The coastal area of ​​Fujian in my country is prone to typhoons. In history, there have been many super typhoons landed here, all of which caused a lot of damage to local houses. On September 15, 2016, at 3:5 in the morning in Xiang'an District, Xiamen City, the maximum wind force near the center of the Pacific No. 14 super typhoon "Meranti" reached level 17 or above (68m / s), which is the first typhoon since the founding of the People's Republic of China. The strongest typhoon that has landed in southern Fujian since then has caused super serious damage to the areas along the way, especially light steel buildings, road trees, signs, and billboards. The powerful wind of this super typhoon caused heavy economic losses along the way. The assessment of the ph...
