鉄筋コンクリート造建築物の壁・梁・スラブにおけるかぶり厚さの分布に及ぼす打増しや施工方法の影響

A quantity of sample members of the 18 buildings were investigated for cover concrete thickness to analyze its distribution. This paper summarizes the results of analysis of the influences of “additional cover concrete in construction phase” on the walls and undersurfaces of beams as well as the influences of the construction method by preliminary bar arrangement for the beams. “Additional cover concrete in construction phase” results in larger deviations both within each member and among members. The construction method by preliminary bar arrangement leads to smaller deviations both within each member and among members at lateral surfaces of beams.
