Abstract: The recent terrorist attacks around the world have prompted the respective authorities to address the risks to the critical infrastructure. Precast construction has become increasingly common in the Kingdom of Saudi Arabia because of its speed, which is extremely desirable due the current high rate of development in the Kingdom. In general, buildings are extremely vulnerable to progressive collapse if some of the columns are lost due to blast exposure. As precast buildings lack structural continuity and redundancies in the load paths, they are even more susceptible to progressive collapse than cast-in-situ monolithic buildings. Thus, to avoid catastrophic events, it is important to study the likelihood of the progressive collapse of precast structures in the Kingdom. In this study, the behavior of two different half-scale precast specimens were studied experimentally under middle column removal scenario. These specimens were designed to represent the most common types of exiting precas

Abstract: The main object of this paper is to fit with high degree of accuracy the true structure response by considering the concept of interface element which is used to simulate three dimensional soil-structure interaction in the dynamic analysis, therefore the dolphin of khor Al-Amaya berth no. 8 is analyzed as a case study. The (p-y), (t-z), and (q-z) curves which are adopted by American Petroleum Institute (API) are used to find normal and tangential interface moduli and end bearing modulus. For this purpose, a computer Fortran program Offshore_Inter has been built to obtain the required solution. The subspace iteration method is used to find the free vibration solution while Newton-Raphson modified method combined with Newmark’s method is applied to get the nonlinear forced vibration solution. For both solutions, the conjugate gradient algorithm is used as a solver of the dynamic problem. A parametric study has been carried out including different soil type, soil engineering properties, l
