ETABS荷载工况与加载定义及施加方法

"ETABS Load Cases, Combinations, and Loading.pdf" is a comprehensive guide that covers the various load cases, combinations, and loading methods in ETABS software. In the eighth chapter of the document, the focus is on defining load cases, load combinations, and applying loads in ETABS. The first step in handling applied loads is to define load cases and assign specific loads to each load case. ETABS offers a variety of load cases, including static load cases, response spectrum load cases, time history load cases, static nonlinear pushover load cases, and construction sequence load cases. Static load cases are further categorized into dead load cases, live load cases, seismic load cases, wind load cases, snow load cases, among others. ETABS can automatically generate design load combinations according to relevant national codes, but engineers also have the flexibility to define custom design load combinations as needed. The chapter delves into the methods of defining static load cases, response spectrum load cases, wind loads, and design load combinations, as well as the application and display of loads. ETABS' approach to defining load cases is characterized by flexibility and scientific rigor, allowing engineers to manipulate load parameters and have a deep understanding of each parameter in order to effectively control load definitions. Defining static load cases is a crucial step before conducting structural analysis. There is no limitation on the number of load cases that can be defined in ETABS, enabling engineers to separately examine the effects of specific loads on structural forces and deformations. Overall, the chapter provides valuable insights into the definition of load cases, load combinations, and loads in ETABS, emphasizing the importance of understanding and accurately defining these parameters in order to ensure comprehensive structural analysis and design.
