    Abstract: This paper tends to evaluate the behavior of five- story RC building with and without floating columns using RC frames as lateral resisting system. This investigation had been carried-out using ETABS Ultimate V.18.1.1. The defined load cases, load combinations, the equivalent static lateral load pattern, and the response spectrum function were defi... Show More

    Abstract: The determination of the most critical non-circular slip surface can be attributed to the optimization of complex non-linear multi-peak function due to its numerous control variables and large amount of calculation. It is a trend in recent years to apply intelligent optimization algorithm into slope stability analysis. Considering that the standard... Show More
