Temperature and Stress Analysis of An Experimental Model of Prestressed Lightweight Concrete Platform

摘要

This paper presents an experimental study of a prestressed lightweight concrete platform model with a tank and five steel-columns. This platform can be used not only for extraction but also for storage ofoil and is suitable tor the Bohai Sea and other shallow seas of China. The platform is subjected to tem perature, load, or both. The corresponding temperature distribution, strains, cracks, and vulnerable parts of the platform are analyzed respectively. By use of the finite elemenl method and empirical formulas, the temperalare field of the model is analyzed. The results agree with the experimental results, thereby verifying the reliability of these two calculating methods. The paper provides an experimental basis for the design of the bearing capacity and normal service state of prestressed concrete platforms.
