ABSTRACT
Three-dimensional (3D) square cylinders and similar structures, which are one of the common shapes in wind engineering, are widely used in high-rise buildings and other structures (Quan, Chen et al. 2010). The flow around the 3D square cylinders and the wind pressure distribution are worthy to be discussed further (Hui, Tamura et al. 2012, Chen, Xiao et al. 2012, Huang, Zhu et al. 2012, Quan, Zhang et al. 2012, Shen, Wang et al. 2012, Tang, Jin et al. 2012, Wang, Shi et al. 2012, Zou, Liang et al. 2012, Hui, Tamura et al. 2013, Hui, Yoshida et al. 2013, Gu, Zhang et al. 2013, Zhang, Quan et al. 2013). Considering as the hot issues in recent years, the flow characteristics and wind loads distributions are essential to wind engineering, and the interference effects of double square cylinders remain unclear so far (Xie and Gu 2004, Xie and Gu 2007).
