Project title:Dynamic Performance of Tall Reinforced Concrete Buildings Subject to Wind Load

This study focuses on the dynamic response of multi-storey buildings, in particular tall reinforced concrete buildings, under lateral loading, e.g. wind. These buildings can be designed in various types of structural systems based on many different factors that should be taken into account through adopting appropriate structural systems. These factors include the height of the building, the geometry and plan of the building, the properties of construction materials, the dimensions of structural components, the applied loading, the predicted structural responses, etc. Thus, this research will apply the finite element method as the main methodology to investigate the factors mentioned above and other factors in comprehensive parametric study so as to establish the most effective parameters on the dynamic behaviour of tall reinforced concrete buildings. In addition, the most popular international wind design codes and standards will be summarised and evaluated in more detail to identify the current scarcities in evaluating the structural responses of tall buildings by comparing different provisions related to the ultimate limit design issues in terms of load effects such as bending moments and shear forces, and the serviceability limit design issues in terms of modal frequencies, displacements, accelerations, and even jerks. Also, the possibility of establishing a universal wind design code will be explored based on the current development of simulating the wind induced effects on structures. Moreover, the proposed analytical methods in literature will also be investigated to assess the reliability in evaluating the structural responses of multi-storey buildings under lateral loading. In combination with the two current methods, it can be a significant basis to compare the predicted structural responses of tall reinforced concrete buildings with various structural configurations under the effects of wind loading and to explore the possibility of providing such appropriate proposed models.
