Abstract

This paper introduces the failure law of the floating structures by an engineering examples of the up-floating accident. The reasons of the accident are insufficience of anti-floating anchor rod, short of the length of anchor rod and early termination of precipitation, according to the analysis about the design and the construction information. Through the new anti-floating anchor and new reinforced concrete slab, the whole anti-uplift and partial anti-uplift of underground parts of the floating structure are strengthened. The frame columns and beams with cracking damage caused by the up-floating accident are strengthened with enlarging section method and the enclosure steel method.
