Das eine Reihe an bekannten Benchmark-Szenarien für Windsimulation vorgestellt。 Der Nachfolgende Beitrag dreht sich dabei um den “案例 A - 高层建筑,形状为 2:1:1”。 Im Folgenden wird das beschriebene Szenario in RWIND2 nachgebildet und die Ergebnisse mit den simulierten und derexperimentellen Resultate des AIJ verglichen.
在 1990-1/NA/A1:2012-08 的基础上,根据 DIN EN 1992-1-1/NA/A1:2015 设计了一根钢筋混凝土柱,其常温下承载力承载力(ULS)是正常的。 本设计采用名义曲率法;见 DIN EN 1992-1-1,章节 5.8.8。 该柱位于三跨框架结构的边缘,该结构由 4 根悬臂柱和 3 个铰接在柱上的独立桁架组成。 柱子承受垂直方向的荷载,预制桁架的作用是雪荷载和风荷载。 将结果与文献进行了比较。
货架支架采用工字形截面。 The axial rotation is restricted on both ends while warping is enabled. The structure is loaded by two transverse forces in the middle. The verification example is based on the example introduced by Gensichen and Lumpe.
由四根倾斜杆件和一个竖向杆件组成的平面桁架,在上部节点处施加竖向力和与平面外的力。 Assuming the large deformation analysis and neglecting the self-weight, determine the normal forces of the members and the out-of-plane displacement of the upper node.
验算示例描述了作用在建筑物模型上多个风向的风荷载。 The model consists of eight cubes. The velocity fields obtained by the RWIND simulation are compared with the measured values from the experiment. The experimental data are measured using a thermistor anemometer in the wind tunnel.
验算示例描述了作用在建筑物地面墙壁上的压力荷载。 The buildings are simplified to rectangular objects and scaled down while maintaining the elevation ratios. The pressure distribution on the walls of the model of a medium-high building was conducted by an experiment. The chosen results (pressure coefficient Cp) are compared with the measured values.
验算示例描述了城市街道中的高层建筑周围流动(按比例模型)。 The example is given by the Architectural Institute of Japan (AIJ). The chosen results (velocity magnitude) are compared with the measured values.
