The multiple stable sections are selected and obtained, so that the interference of extreme environment information in special time, such as the situation of extremely high wind pressure like typhoon, can be avoided, and the extreme environment information cannot be used as the data basis for evaluating the stability of the curtain wall structure. The slope preset value can be set by those skilled in the art according to actual service requirements.

particularly, in the design and construction process of the curtain wall structure, the design of the building structure needs to be considered, for example, the gallery part of the building structure, the curtain wall structure cannot be directly fixed on the building structure, and a frame needs to be used for fixing and supporting, so that the stress borne by the curtain wall structure at the position is large, and the requirement on stability is high. And, areas such as drainage and ventilation channels of the building structure need to be communicated with the outside, the curtain wall structure also needs to be designed in an auxiliary way, the performance of the curtain wall structure is also required to be prevented from being influenced by problems such as water leakage, and the stability requirement of the curtain wall structure at the position is higher.
Based on the above, the curtain wall structure needs to be subjected to mechanical analysis and evaluation, and areas with different stress strength and stability requirements of the curtain wall structure are obtained.
As shown in fig. 2, step S400 in the method provided by the present application includes:
s410: acquiring design drawing information of a building structure, wherein the lattice curtain wall structure is constructed on the building structure;
s420: constructing a building structure virtual model based on the building structure design drawing information;

The building structure virtual model can reflect the information of the whole construction, the size and the like of the building structure.
According to the building structure virtual model, a plurality of building level deformation areas are obtained, wherein the building level deformation areas comprise areas with distance change on continuous surfaces of the building structure, and the continuous surfaces can be vertical surfaces, curved surfaces, flat surfaces and the like. Exemplarily, the building level deformation region includes areas such as galleries, balconies, windows, and at the periphery of the building level deformation region, the curtain wall structure needs to be provided with a fixing frame for fixing, and cannot be fixed on the surface of the building structure, so that the stress is concentrated, and the requirement on stability is higher.
According to the building structure virtual model, a plurality of building function areas are obtained, wherein a building function area refers to an area on a building structure which needs to support part of building functions, and the building functions can be as follows: functions such as ventilation, drainage, daylighting need build the facility that satisfies above-mentioned function on building structure on corresponding building function region, can influence curtain wall construction's normal structure to, building function region can produce the vibration at the in-process that carries out above-mentioned function, more influences curtain wall construction's stability, and consequently, building function region's curtain wall construction receives the stress bigger, and is higher to curtain wall construction's stability requirement.
And obtaining a grade analysis result of the lattice curtain wall bearing area based on the plurality of building grade deformation areas and the plurality of building functional areas. The method comprises the following steps of constructing a plurality of building function areas on the basis of a building level deformation area, wherein the building level deformation area and the building function areas can be partially overlapped, different requirements for the structural stability of the curtain wall can be set according to different conditions of each area, and the different requirements can be used as a data base to carry out subsequent evaluation on the structural stability of the curtain wall. The stability of the curtain wall structure is evaluated based on different areas of the building structure, the data dimension of the stability evaluation analysis of the curtain wall structure can be improved, and the accuracy of evaluation is improved.

For example, curtain walls under rain and laterally under a building structure are less strongly affected by ultraviolet environmental information. And the strength of the curtain wall structure on the leeward side of the building structure, which is influenced by the wind pressure environment information, is small. Therefore, service strength evaluation of each region of the curtain wall structure needs to be performed based on the service environment information of the lattice curtain wall and the virtual model of the curtain wall structure, and the strength of each region affected by the service environment information needs to be analyzed and evaluated.

Then, based on the curtain wall structure virtual model, a plurality of regions in the model are obtained, exemplarily, the regions can be divided according to various rules, wind pressure service region division is performed on the basis of service environment wind pressure information and comprises a plurality of leeward regions, a plurality of surface wind regions and the like, and rainfall service region division is performed on the basis of service environment rainfall information and comprises a plurality of rainfall regions and a plurality of shielding regions. The sheltered area is an area which is not affected by rainfall due to the sheltering of building structures such as rain shields or rooftops. The multiple regions can also comprise multiple regions with different service intensities, for example, under the wind pressure information of the service environment, due to different heights of the regions of the curtain wall structure or shielding of surrounding buildings, the multiple regions with different wind pressure intensities comprise multiple regions with different rainfall intensities and ultraviolet intensities, and similarly, the multiple regions with different rainfall intensities and ultraviolet intensities also comprise multiple regions with different ultraviolet intensities.
