Prediction of cracks in concrete frames by finite element modeling

In recent years, the employment of computer techniques in engineering design work has become an irreversible trend. This is achieved through using computer as the tool for modeling, analysis, and design. The objective of this paper is to determine the stress in unreinforced concrete portal frame and predict the cracks which will occur in the beam and columns in this frame due to this stress. To do this, a technique utilizing finite element analysis is used in order to create computerized model using shell elements with SAP2000 program. This model is built to simulate the real state of beam and columns in the frame under different loading conditions.
