In this Project, a constant bolted frame were modeled which the location of the center joint between internal links, varied considerably. The finite element analysis were performed to consider the amount of total displacement in accordance with the center joint location.

In this project, an algorithm has been written with use of Mechanical APDL to eliminate the elements which carry the least loads in each optimization stage. After some killing steps, the model would get the lightest weight with the same load capacity as the whole model.

To increase knowledge about motorway bridges' safety with regard to blast demolition, a study has been conducted on several bridges with variable distance to explosive materials.

Blast doors were extra doors that were closed next to a room's regular entrance or other closed door to provide extra reinforcements against hostile forces such as explosives,powerful blasters.

In this project a finite element analysis was performed to evaluate the following items with regard to a chimney destruction using TNT explosive materials:
