Reinforced concrete surface design for slabs, plates, and walls is possible in the RF-CONCRETE Surfaces module according to the ACI 318-19 or the CSA A23.3-19 standard. A common approach for slab design is the use of design strips for determining the average one-way internal forces over the width of the strip. This design strip method essentially takes a two-way slab element and applies a simpler one-way approach to determine the required reinforcement needed along the strip length.
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.
Requirements for the design of structural stability are given in the AISC 360 – 14th Ed. Chapter C. In particular, the direct analysis method provisions, previously located in Appendix 7 of the AISC 360 – 13th Ed., are described in detail. This method is considered an alternative to the effective length method, which in turn eliminates the need for effective length (K) factors other than 1.0.
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.
