Gravity Effects in Small-Scale Structural Modeling: Analytical and Experimental Approach

Abstract

An analytical investigation and laboratory study on gravity effects in small-scale modeling have been performed. The appropriate scaling length for ground movement is identified as l=G/(rho g), when gravity effects are important. Dimensionless gravity parameter, rho lambda/G, and impact energy parameter, WH/(G lambda.cubed), are identified as the key governing parameters for the problem. Laboratory techniques and procedures have been developed for compensating gravity effect without using artificially induced gravity. Experimental results were summarized in twelve tables and twelve graphs. Keywords: Rayleigh waves; Dynamic loading; Strain energy; Soil mechanics; Impact energy; Gravity potential energy; Small scale modeling.
