Verification on the Compressive Behavior of Corrugated Steel Plates due to Details of Bolted Lap Joint

Abstract

This study is dealt with the experimental seam strength of deep corrugated steel plate which is used as underpasses, storm sewers and other buried applications. The soil-metal structure using deep corrugated plate should be sufficient to ensure safety for compressive loading. The experimental and theoretical results on the seam strength are accumulated enough to take the design guideline, even if the seam strength at the bolt connected lap joint in construction site can be varied depending on the connection detailing and the thickness of plate. In this study, compressive behavior of bolted lap jointed plates using various connection detail such as gasket, slot hole, washer was experimentally analyzed. From the test, failure pattern with an increases in the thickness of specimens was changed from plate bearing to bolt shearing. In case of thicker plates than 6.0mm, the structural performance of lap joint using gasket and slot hole is more effective than it of the plate adopted washer.

Analytical Study on Structural Behavior of Bolted Connections in Corrugated Steel Plate Structures

“…. 한편 주로 유한요소법을 이용한 해석적 연구에서 있어서도 볼트 이음부의 구조 거동을 합리적으로 모사할 수 있는 유한요소 모델을 도출하려는 연구가 미흡했 다고 판단된다 (Kang, 2004;Lee, 2012 (Oh and Nam, 2012). 하지만 파형강판 구조물 볼트 이음부에서 발생하는 손상의 주요 원인이 압축 거동보다는 휨 거동과 관련된다는 점이 파악됨에 따라 볼트 이음부 검토를 위해서 압축 실험과 더불어 휨 실험을 실시하는 경우가 증가하였다 (Choi, 2005;Lee et al, 2007) (Bakht and Agarwal, 1988;Mikhailovsky et al, 1992…”
