This project documents include test data and photographs from seven single-bolted lap joint tests that were conducted at ambient temperature, 400 deg Celsius and 600 deg Celsius. The purpose of these tests was to investigate the effects of bolt diameter and plate thickness on plate bearing behavior at 400 deg Celsius and 600 deg Celsius. Each single-bolted lap joint specimen consisted of one ASTM A325 bolt and two ASTM A36 plates. Additionally, three-dimensional (3D) finite element models were developed to predict the behavior of the single-bolted lap joints. The models were benchmarked using experimental results from the plate bearing tests. The project documents also include the results from the finite element analysis (FEA), and comparisons of the load versus displacement curves measured experimentally with those predicted analytically.
