    • Vibration-Based Damage Identification Method Using Modified Back-Propagation Neural Networks 

      Jin, Hai; Nan, Fei; 金海 (ADV MATER RES-SWITZ, 2011)
      This paper presents a damage detection method using a combination of global (changes in natural frequencies) and local(displacement mode shapes) vibration-based analysis data as input in neural networks for location and ...
    • Wind load characteristics of a long-span retractable roof structure 

      Zhang, Jian Guo; Zhuang, Hui Min; 张建国 (Trans Tech Publications, 2014)
      Taking a long-span retractable roof structure, which locates in a coastal city of China, as an example, a wind tunnel test on a rigid model was carried out. This paper analyzes the wind load characteristics of this structure ...
    • Wind tunnel test of symmetrical twin-tower tall building model 

      Zhang, Jian Guo; Zhuang, Hui Min; 张建国 (Trans Tech Publications, 2014)
      In this paper, taking symmetrical twin-tower tall building model as an example, a wind tunnel test with simultaneous surface pressure measurement, in 7 wind directions, was carried out. Integration of the surface pressures ...
    • Wind tunnel test of tall buildings with irregularities of elevation 

      Zhang, Jian-Guo; Zhuang, Hui-Min; 张建国 (Trans Tech Publications Ltd, 2014)
      In this paper, 2 high-rise building models with ladder and cascade irregularities of elevation were tested in a wind tunnel respectively to measure the mean and fluctuating wind pressure distributions. The mean and RMS ...
    • Wind-induced vibration control of Benchmark model with damper 

      Fan, Hui Neng; Lin, Qian; Zhang, Jian Lin; 张建霖 (Trans Tech Publications Ltd, 2013)
      Based on 76-storey Benchmark model, the optimization objective including displacement reduction index and acceleration reduction index is given under the effect of wind-induced vibration, by which kinds of dampers are ...
    • Working mechanism of two-phase varying stiffness piled raft foundation 

      Huang, Yuan; Feng, Xin-Jian; Zhang, Jian-Lin; Lin, Shu-Zhi; 张建霖 (Trans Tech Publications Ltd, 2014)
      In this paper, the FEM software ABAQUS is used to analysis the pile-soil load share ratios, load share value of pile side friction and tip resistance for three bases, including natural raft foundation, conventional piled ...
