| Research Abstract |
In this project, we would propose the estimation method of multiple bolted connection loaded perpendicular to the grain in timber engineering. Considering the arrangement of bolts in a joint, we could image the followings, with blots in multiple-row, with a few bolts in a row and with gridded ones. Then we conducted loading tests with those types and applied the new strength-estimation method proposed by our past study. As a result, we could confirm that the method is useful to estimatethe crack initiation strength of multiple bolted connections loaded perpendicular to the grain
