A STUDY OF STATIC AND DYNAMIC RESISTANCE AND BEHAVIOR OF STRUCTURAL ELEMENTS,
Abstract
This research program is being conducted to determine the behavior of a number of simple structural models when they are embedded in a soil medium which is subjected to static and dynamic loads. During the first year of the program, covered by this report, techniques were developed for making the determinations and studies were conducted on four cylindrical shell models under static conditions of loading. Three of the models had hemispherical end closures and diameter-thickness ratios (D/t) of 40, 80, and 160. The fourth model had a D/t ratio of 80 and an end closure system which could not transmit load to the shell. Most of the work was conducted using a dry cohesionless soil medium of uniformly graded silica sand (Ottawa sand). The model with hemispherical heads and D/t ratio of 80 was also studied in a cohesive soil medium of silty clay. The experimental analysis of the behavior of the central transverse plane of each shell is presented. Some conclusions are drawn regarding the influences of model stiffness, soil media, overpressure level, and end closure system on the hoop and longitudinal membrane forces and bending moments in the shells.
