ANALYTICAL STUDY ON BEHAVIOR OF RC BOX CULVERT SUBJECTED TO FAULT DISPLACEMENT

In this paper, analytical studies on behavior of RC box culvert subjected to fault displacement are con-ducted. The fault is set as reverse fault which dip angle is 67.5 degree, and parametric studies about hori-zontal intersection angle of structure and fault are presented. As a result, intersection angle near to a right angle generates larger longitudinal axial forces, while it with an acute angle causes larger cross-section bending moments. In this papers condition, concrete and rebar stresses stay under their respective yield stress when fault displacement is 0.1m, and some concrete and rebar stresses reach yield stress when fault displacement is 0.2m.
