扁平な大型rcシェルの長期性状と構造特性に関する実証的検討

Abstract

In general, long-term creep deformation and other factors affect the structural properties of arches and shells with large spans and low rises, but there is little information available. Existing structural design guides make assumptions based on limited information. In this study, we tracked the deformation of the large shell of the actual machine for 10 years from the time of construction, and identified the expansion, contraction, long-term creep, temperature deformation, and vibration characteristics immediately after placing concrete by measurement and numerical analysis. We will report on a case where we tried to comprehensively analyze the effects on the structural characteristics.
