走行荷重が作用するUFC埋設型枠RC床版の最大耐荷力および耐久性に関する研究

抄録

The objective of this experimental study is to evaluate the practicality of RC slabs with the UFC permanent forms. Two types of test specimens, i.e. RC slab using ordinary forms and RC slab with UFC permanent forms composite structure, were prepared and subjected to a static load test, running load test, fixed point fatigue load test, and running load fatigue test. As a result, the load-carrying capacity and the number of loading cycles of the RC slabs with the UFC permanent forms were 1.2–1.4 times and 6.3 times larger than those of the RC slabs using ordinary forms, respectively. This is due to the cross-linked steel fibers that have the effect of controlling cracking and forming the bond surfaces with irregularities, which in turn have the effect of improving the bond between RC slabs with UFC permanent forms. It can be demonstrated that the RC slabs with UFC permanent forms have applicability as a composite structure highly resistant to fatigue.
