초록

This study relates to an experimental research to review utility of removable steel Eco deck plates by connecting them with bolts in order to prevent corrosion in the weld zone and to reduce maintenance and repairing cost of slab. The results of economic feasibility of Eco deck plate and LCC by way of evaluation of safety against construction load are as follows.
(1) Test specimen 150-ED3-3.8 was finally broken into other forms with different behavior from other specimens. However, behavioral characteristics of test specimens were not much affected by final broken shape changes. (2) Allowing deflection by construction load was found as 85.5% of design value for the specimen 135-ED1-3.2, 90.9% for the specimen 150-ED3-3.8, and 75.9% for the specimen 200-ED5-4.5 showing safe in the allowing deflection for all the test specimens. However, it is judged to be necessary to adjust camber value in case of test specimen 150-ED3-3.8 having allowing deflection around 90%. (3) The comparison results between general deck plate and LCC having same specification about purchase cost including manufacturing and installation and cost during use including maintenance and dismantle showed that all the specimens used in the experiments were economical by around 16.62∼18.99% as compared with that of LCC.
