The design process of Space Frame structure

--

The design of the space frame structure is an important task. Designers need to reasonably optimize the space frame design in accordance with the relevant national standards and requirements and highlight the characteristics of the space frame structure. When designing the space frame structure, the model analysis method can be used to make reasonable calculations for the space frame, and the construction drawings must be adjusted.

1) Model analysis. In order to ensure the rationality of the model, construction designers need to reasonably divide the initial network size, select the appropriate thickness of the space frame, make reasonable adjustments to the plane support, and find the key points of construction. At the edge of the space frame, the position of the support needs to be adjusted. This process needs to follow the principle of repeated adjustment, and also meet the requirements of the building shape. Combined with the characteristics of the space frame, it is necessary to ensure that the model meets the design requirements of the drawings.

2) Calculation of space frame structure. When calculating the space frame, it is mainly to optimize the design of the support setting, the load input, and the combination of the working conditions. During the design process, the calculation results should be combined to adjust the construction process of the design scheme and check the input of the wind load. Whether it is accurate or not, simulate the bearing components to judge whether the setting of the bearing components is reasonable under the combined state of the working conditions and whether the setting of the sub-item coefficients is accurate enough. When checking the deflection of the calculated structure, its normativeness should be ensured, and unreasonable places should be adjusted. When checking the geometric variability of the space frame structure, it is also necessary to check whether the size of the bolts connecting the nodes meets the design requirements.

3) Adjustment of space frame construction drawings. When adjusting the construction drawing, it is necessary to calculate the construction drawing of the node and draw the drawing for the processing construction. The horizontal space frame is based on the horizontal plane, while the curved space frame is based on the fitting plane. At the intersection of the arcs, other datum planes should be used for calculation. When designing the space frame model, professional calculation software will be used, and the position of the plane needs to be moved to the base point position to avoid excessive errors in the drawing, which will affect the installation of the space frame ball. The adjustment of construction drawings can ensure the quality of space frame structure building design and construction.
