Abstract
Bending test of reinforced concrete beams using materials imported from Southeast Asia were tested to evaluate the non-contact lap splice length of longitudinal bars encased in grouted corrugated ducts. The test results showed that strengths and deformation capacities of the specimens with a lap splice length 20 times the bar diameter were almost the same as without lap splices. Then, a seismic test of a precast column with a lap splice length 30 times the bar diameter was carried out under varying axial loading. Test results revealed that the strength exceeded the calculated strength and the attained ductility was adequate.
