The Appraisal and Strengthening Design of a Large Adding Layer Supermarket

Abstract:

This paper takes a large supermarket as the research object. Based on its adding layer directly without identification, these implementations including reviewing design drawing, witnessed inspections, indoor test and theoretical analysis are carried. The identification results show that: the layer-adding design has a serious problem on the conception; part of the foundation's short concrete column misplaced seriously to its upper concrete column whose maximum is up to 50mm, and between the gap, there are some obvious weak positions existing some crossing pipelines which are filled completely with cement mortar; part of the concrete column's tails have serious phenomenon of cellular pits; the upper steel structure's support system is imperfect and unreasonable; the seismic capability of the blindly adding layer structure could not meet the national code's requirements. Based on the above structure defects, this paper ensure the safety of the adding layer structure through sticking steel's reinforcement method, section enlargement method and adding some structure 's support system.
