COMPUTATION OF DYNAMIC PASSIVE EARTH PRESSURE USING LISP

Few solution techniques exist to determine the dynamic passive earth pressures for cohesionless soils. The pseudostatic dynamic Mononobe-Okabe equation is widely used to design structures that must resist earthquake loads; however, this equation assumes a planar failure surface, which is not the most critical mode of failure in determining passive failure load. Researchers have attempted to develop a more accurate method for computing pseudostatic dynamic passive earth pressures. This paper describes the development of a computer-program-based solution assuming a log-spiral failure surface to compute pseudostatic dynamic passive earth pressure coefficients. COMMON LISP--a programming language--was used to develop the code. The features and capabilities of COMMON LISP are not widely known outside the field of computer science. Some features and capabilities are demonstrated in the formulation and solution of computationally intensive algorithms.
