Abstract
본 연구의 목적은 지진모의실험을 위한 1:5 축소 10층 R.C. 공동주택 모델의 제작과정을 통하여, 실험체의 효율적인 설계 및 제작 과정을 개발하는 것이다. 실험체의 축소율은 가용한 진동대의 크기(<TEX>$5m{\times}5m$</TEX>)와 최대 허용무게(600kN)및 모델 철근(D3 볼트, <TEX>${\phi}2$</TEX> 강선)의 경제성과 상용성을 고려하여 결정하였다. 모델 철근은 현장에 바로 설치하기 어렵기 때문에 철망을 제작한 후 현장에서 조립하였다. 벽체와 슬래브를 동시에 타설할 경우 거푸집의 탈형이 매우 어렵기 때문에, 벽체를 먼저 타설하고 양생 후 탈형한 뒤 슬래브 거푸집을 설치하였다. 벽체 거푸집은 반복 사용이 가능한 Slip form 형태로 한쪽은 합판, 다른 한쪽은 아크릴로 제작하여 타설시 밀실도를 확인할 수 있도록 하였다. 1:5 축소 10층 R.C. 공동주택모델을 제작하기 위해 총 제작 기간은 약 6개월이 소요되었으며, 전임 연구원 5명, 작업보조원 612명 일의 인원이 투입되었다. The purpose of this study was to develop an efficient process in the design and construction of a 1:5 scale 10-story R.C. apartment building model for an earthquake simulation test. The reduction ratio of the specimen was determined by the size (<TEX>$5m{\times}5m$</TEX>) and pay load (600kN) of the available shaking table and the availability of model reinforcements. For efficiency and quality control of the reinforcement work, prefabrication was used. Construction was conducted in two steps, the wall in one step, and another step for the slab, because it was impossible to remove the formwork of a wall if the walls and slabs in a story were constructed in one step. The slip form construction method was used repetitively for walls. The formwork of a wall was made with veneer and acryl plate on each side, so it was possible to check the quality of the concrete placing. To construct this model, it took roughly six months with five full-time research assistants, for a total of 602 man days of labor in construction.
