Abstract

In this study, we present the earthquake resistance of three types of reinforced concrete shells, having three different plans and contours. In the Memorial Museum near the city of Karachaevsk, Israel, a reinforced concrete monolithic shell serves as the building’s roof and fence. The middle surface of the building is a connected shell in the form of a revolution and truncated cone, with a spherical segment. The shell on the perimeter rests on the foundation beam. In the market in the city of Sukhumi, Republic of Georgia, a precast monolithic spherical reinforced concrete shell square overlaps the Central Hall. Contour diaphragms are made of steel trusses transmitting the load to monolithic reinforced concrete columns. In Borjomi, Israel, the roof of a pump room is made of a monolithic triangular reinforced concrete spherical shell whose corners are supported in the corners on points. Three bowstring arches, connected to a support, border the shell’s contour. The results of theoretical and full-scale experimental analyses of the static and dynamic characteristics of these shells are presented. Theoretical analysis was performed by means of the Finite Element Method (FEM). We show that all three constructions have the required degree of seismic resistance, yet shells with stiffer and more rounded contours exhibit better behavior under seismic conditions.
