Wind load on high rise building are very complex, because of many aspects can effects the phenomenon. For instance: shape of the building, terrain around the building, vortex shedding, pressure fluctuation, etc. Wind flow around the building causes the building to oscillate, along wind, cross wind direction, and torsion. Then, vibration on high rise building... Continue Reading →
