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.
期刊介绍：
The Architectural Institute of Japan’s Journal of Structural and Construction Engineering aim to pursue theories for building and maintaining pieces of architecture as well as the cities or areas surrounding them, and to accumulate and systematize the knowledge needed to put those theories into practice. The Journal of Structural and Construction Engineering focuses on research results in the specific fields of “building materials and construction” and “structures.” Accordingly, it compiles articles in the following areas, disseminates relevant information, and hosts discussions: ・Concrete, steel, and inorganic materials ・Timber and organic materials ・Finishing materials ・Construction and quality management ・Applied mechanics ・Loads and reliability on structures ・Building foundations ・Timber structures ・Steel structures ・Reinforced concrete structures ・Shell and spatial structures ・Engineering seismology and structural dynamics ・Other composite structures
