创建计算流体力学 (CFD) 验证示例是确保模拟结果准确性和可靠性的关键步骤。 This process involves comparing the outcomes of CFD simulations with experimental or analytical data from real-world scenarios. The objective is to establish that the CFD model can faithfully replicate the physical phenomena it is intended to simulate.
The National Building Code of Canada (NBC) 2015 Article 4.1.8.7 provides a clear procedure for earthquake methods of analysis. The more advanced method, the Dynamic Analysis Procedure in Article 4.1.8.12, should be used for all structure types except those that meet the criteria set forth in 4.1.8.7. The more simplistic method, the Equivalent Static Force Procedure (ESFP) in Article 4.1.8.11, can be used for all other structures.
Mit Hilfe der Modalanalyse in DYNAM Pro - Erzwungene Schwingungen kann für periodisch angeregte Strukturen die stationäre Systemantwort ermittelt werden. Das ist von Vorteil, wenn nur der eingeschwungene Zustand der Struktur von Interesse ist. Anstatt der vollständigen Lösung der Bewegungsgleichung wird nur die spezielle Lösung ausgegeben.
Using the RF-TIMBER CSA module, timber column design is possible according to the CSA O86-19 standard. Accurately calculating timber member compressive resistance and adjustment factors is important for safety considerations and design. The following article will verify the factored compressive resistance in the RFEM add-on module RF-TIMBER CSA, using step-by-step analytical equations as per the CSA O86-19 standard including the column modification factors, factored compressive resistance, and final design ratio.
Using the RF-TIMBER CSA module, timber beam design is possible according to the CSA O86-14 standard. Accurately calculating timber member bending resistance and adjustment factors is important for safety considerations and design. The following article will verify the factored bending moment resistance in the RFEM add-on module RF-TIMBER CSA using step-by-step analytical equations as per the CSA O86-14 standard including the bending modification factors, factored bending moment resistance, and final design ratio.
In einem System können zahlreiche Nichtlinearitäten vorhanden sein. Um diese in einer Dynamischen Analyse realitätsnah abzubilden wurde das Zusatzmodul RF-DYNAM Pro - Nichtlinearer Zeitverlauf entwickelt. Zur Anwendung des Zusatzmoduls wird im Folgenden die Vorgehensweise anhand eines Beispiels beschrieben.
美国木材协会(AWC)发布了 2018 年版的木结构国家设计规范(NDS)。 This is the second edition of the NDS to contain a chapter dedicated to cross-laminated timber (CLT) design. Therefore, a couple of revisions were included in the 2018 NDS when compared to the previous 2015 Edition.
对于承载能力极限状态设计,EN 1998-1 2.2.2和4.4.2.2 [1] 中要求计算考虑二阶效应(P-Δ效应)。 Dieser Einfluss darf nur vernachlässigt werden, wenn der Empfindlichkeitsbeiwert der gegenseitigen Stockwerksverschiebung θ kleiner 0,1 ist.
