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.

关于扁平的大型RC壳的长期性状和结构特性的实证研究

一般来说，长期蠕变变形等因素会影响大跨度低高程拱壳的结构性能，但相关资料很少。现有的结构设计指南基于有限的信息做出假设。在本研究中，我们从施工之日起对实际机的大壳进行了10年的变形跟踪，并通过测量和数值分析确定了混凝土浇筑后的膨胀、收缩、长期徐变、温度变形和振动特性。我们将报告一个案例，我们试图全面分析对结构特征的影响。

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
