3D-FEM-Analysis on the Seismic Behavior of Foundation Piles and Soil Structure Interaction

This research deals with the study of the behavior of piles under the influence of seismic loads through (3D) modeling using FE-Method-program (ABAQUS) with special reference to the most important parameters affecting the displacements and internal forces generated in piles. This study has been completed in two phases: the first phase is a case study of the single Pile (reference case), where a study of the behavior of a single pile assigning structure is modeled with a degree of freedom. The parametric study results show that the presence of structure causes the application of a large load in the upper part of the pile resulting from the impact of inertia dominating the kinetic effect. The forces of inertia increases with the increasing mass of structure, and when the frequency of structure nears the frequency of seismic load. The second phase deals with the study of the situation of the group of piles, where the study handles the effect of a number of piles, piles spacing, and locations on the internal force and displacements generated in the piles. The parametric study results have shown for this phase of this research that an increase the number of piles in the group causes a significant increase of internal forces generated at the top of the pile and a slight decrease for those forces in the central part of the pile, that seismic loads are not distributed equally for all piles, and that corner piles are subject to greater loads while mid. Piles are subject to less load.

The Effect of Students' Attitudes Towards Entrepreneurship on Their Entrepreneurial Intentions

This paper aimed to analyze the variables of the Theory of Planned Behavior (TPB) and the Theory of Reasoned Action as the most widely used theories in research on entrepreneurial intentions. A sample (n=406) students from Private and Public Sector Syrian Universities was analyzed using SPSS. Results indicate that the percentage of students who prefer to start an entrepreneurial venture is higher than that of those who prefer to work for the Private or Public Sector upon graduation. Results provide strong support for the intentions of students to start an entrepreneurial venture in addition to the assumption that variables such as ; attitude towards entrepreneurship, subjective norms and perceived behavioral control affect intentions.
