钢筋混凝土超长结构无缝设计研究综述

Discussing of RC superlong structure's jointless design

钢筋混凝土超长结构无缝设计有两个突出问题:一是温度变化、混凝土收缩和徐变对结构裂缝控制的不利影响;二是钢筋混凝土超长结构无缝设计的抗震分析。本文对这两个问题的研究现状进行了简要的概述,并分别介绍了超长无缝结构在温度变化、混凝土收缩及徐变作用下的分析方法和技术措施;超长无缝结构抗震分析方法及抗震措施。最后给出了作者的一点建议。

There were two important issues in the jointless design of RC superlong structure. One was the unexpected efforts caused by the wave of temperature and the shrinkage and creep of concrete and the other was the analysis method of jointless RC superlong structure. In this paper, the author summarized the current situations of these two aspects briefly. Based on this summary, some analysis methods and measures were introduced. Finally, the author gave some pieces of advice about the design of jointless RC superlong structure.
