The results of low velocity impact tests on reinforced concrete panels are presented. These tests were conducted to investigate the behavior of reinforced concrete flexural elements subjected to impact by relatively heavy low velocity objects. The tests consisted of one and two-way elements with simple and restrained supports impacted by weights dropped from varying heights. The program consisted of 17 impact tests with impacts at midspan, near the supports (for one and two-way elements) and near the corners of two-way elements. Six specimens were also tested with static loads at midspan and near supports to provide a comparison of static and dynamic failure modes. The variation of both local damage and structural response with respect to impact location was investigated.
