典型立式轻工业建筑结构抗震性能实例研究

Vertical light industrial building structures exhibit characteristics such as large spans, high-altitude loads, and uneven vertical mass distribution. In order to investigate the vibration response characteristics of this structural form, this paper takes a typical vertical light industrial production workshop as a background and establishes a refined three-dimensional nonlinear computational model. Seismic performance research on this structural form is conducted through finite element simulation technology. The results show that the structure can meet the structural seismic requirements through reasonable design. The structural damage spreads from the outside to the inside. The plastic hinges are distributed more at high levels and less in low levels, and more on heavy load layers and less on non-heavy load layers. In the seismic design process, the heavily loaded floors should be considered as weak floors to be reinforced, and the horizontal and vertical supports should be set in the outer wind-resistant columns to delay the damage of the internal load-bearing members and improve the seismic performance of the structure. In addition, when a large mass ratio variable load exists on the structure, the effect of mass variation on the structural dynamic properties should be considered. When the mass of the equipment is smaller, the interaction between the equipment and the structure can be ignored, and the consolidation model for equipment and structure can be used for simplified calculation during seismic analysis.
