Abstract :

In the study, displacement method.of Finite Element Analysis (FEA) was used to analyze strip footings to obtain maximum actions in designing the footings in accordance with provisions of BS8110 (1997). For this purpose, a computer program that can analyze strip footings using linear FEA was developed. Design example to demonstrate the applicability of the program was included. It was shown among other findings of a sensitivity study that as magnitude of applied colunin moment increased; area of bottom reinforcement required increased, area of top (column face) reinforcement required decreased, and area of transverse reinforcement required remained constant. Also, when the magnitude of applied column moment was doubled, the bottom reinforcement increased with an average value of 8.44%; top reinforcement decreased by about 11.47%; and the animate bearing pressure also decreased with an average value of 11.47%. Based on the results presented, top -einforcement and ultimate soil bearing pressure are the most important design variables of the strip footings .coder increases in applied column moments.
