In this study, several effective parameters and geometrical features were considered to present the design charts and the reduction coefficients tables to obtain the bearing capacity of a strip footing placed near a c-ϕ excavation under static and seismic conditions by using Finite Element Limit Analysis (FELA). The effects of setback distance to footing width ratio (L/B), cohesion (c), soil friction angle (ϕ), pseudo-static horizontal earthquake coefficient (kh), and the height of the excavation to the footing width ratio (H/B) on the bearing capacity and failure mechanism were studied. Also, a design procedure and example of its application were presented to obtain the static and seismic bearing capacities of the strip footing placed near the c-ϕ excavation based on the design charts and the reduction coefficients tables.
