辽滨水城地标建筑造型是一座新颖别致的大跨悬挑建筑结构。鉴于该建筑造型独特(其对风载荷的敏感性),风荷载可能成为一种设计控制荷载,分别从风洞试验及数值模拟的角度对该建筑结构进行风压分布特征的研究。首先,利用风洞试验的方法研究了表面冲孔对蒙皮板风阻系数的影响及不同入射风向角度下该建筑结构表面平均风压系数的变化情况。然后,运用通用计算流体力学软件FLUENT对该建筑结构的简化模型进行了数值模拟,并进一步将数值结果与所对应的风洞试验结果进行了对比,很好地验证了数值模拟方法的有效性。最后,较为系统地总结了该建筑造型的风压分布特征,这对类似建筑结构的风载荷设计有着积极的指导意义。
Liao Bin Shuicheng landmark architectural styling is a novel and unique large-span cantilevered building structure. Due to the unique shape of the building (its sensitivity to wind load), the wind load may become a design control load. The wind pressure distribution characteristics of the building structure are studied from the perspective of wind tunnel test and numerical simulation respectively. Firstly, the influence of surface punching on the drag coefficient of skin panels and the variation of average wind pressure coefficient on the surface of the building under different incident wind angles were studied by wind tunnel test. Then, a generalized computational fluid dynamics software FLUENT was used to simulate the simplified model of the building structure. The numerical results were further compared with the corresponding wind tunnel test results, which validated the effectiveness of the numerical simulation. Finally, the wind pressure distribution characteristics of the building shape are systematically summarized, which has a positive guiding significance for the wind load design of similar building structures.
