摘要

PURPOSE: An underground parking lot construction method using a circular PC column and a TTS slab is provided to cut down on cost and improve work efficiency by preventing overdesign of reinforcing ribs.;CONSTITUTION: An underground parking lot construction method using a circular PC column(10) and a TTS slab is as follows. A mounting part(12) of wide top narrow bottom is formed in the top and center of the PC post. PC beams(20) are placed on the mounting part and fastened by an anchor bolt(13).
