说到 ASCE 7 中建筑结构上的风荷载,可以找到大量的资源来补充设计规范和帮助工程师处理这种侧向荷载。 However, engineers may find it more difficult to find similar resources for wind loading on non-building type structures. This article will examine the steps to calculate and apply wind loads as per ASCE 7-16 on a circular reinforced concrete tank with a dome roof.
Design loads specified in the AASHTO Bridge Design Specification are available in the RF-MOVE Surfaces moving load library. Design Truck (HS-20), Tandem, Type 3, and Overload are available options.
The Steel Joist Institute (SJI) previously developed Virtual Joist tables to estimate the section properties for Open Web Steel Joists. These Virtual Joist sections are characterized as equivalent wide-flange beams which closely approximate the joist chord area, effective moment of inertia, and weight. Virtual Joists are also available in the RFEM and RSTAB cross-section database.
When defining nodal loads, you have several simple options to rotate them:~ Rotation by means of an angle around the global coordinate axes in a certain order~ Orientation at a user-defined coordinate system~ Direction to a particular node~ Alignment by means of两个节点~在杆件/线的方向上
在版本 RFEM 5.04.0024 和 RSTAB 8.04.0024 中,您可以在模块 RF-/TOWER Loading 中定义天线覆冰荷载。 Es stehen Werte aus Herstellerbibliotheken zur Verfügung. Außerdem können Eislasten manuell definiert oder auf Grundlage einer vereinfachten Geometrie berechnet werden.
在 RF-/TOWER load 中对圆形四面塔架和方形三面塔架进行了扩展,增加了力系数。 Die Ermittlung der Kraftbeiwerte für abgerundete Profile erfolgt mit Hilfe der Reynolds-Zahl. Bisher konnte man für vierseitige Maste lediglich kantige Profile und für dreiseitige Maste abgerundete Profile verwenden.
