Abstract
Eksperimentalno istraživanje spojeva od šupljih profila pri udarnom opterećenju
Highlights
Recent developments in the field of civil engineering have been made possible thanks to progress in technology and materials science
Because impact load is a specific loading situation, and as complicated design and analysis steps are required when studying the effect of impact on structural members, it is only recently that appropriate test setups have been developed by researchers
Greater accelerations were obtained on test specimens that were equipped with the joint type 2 in which 10 bolts were used
Summary
Recent developments in the field of civil engineering have been made possible thanks to progress in technology and materials science. Kidd et al performed numerical analyses to validate experimental results of steel connections subjected to drop hammer testing. Different test setups have been developed to investigate behaviour of different materials and structural members under impact [8,9,10,11]. The aim of this study is to investigate behaviour of test specimens under impact load. The main problem is to perform impact tests on specimens manufactured with different joint types. As structural members can be affected by various impact incidents in practice, two different energy levels have been applied to observe the response of test specimens. After completing the experimental study, test results are compared by considering the joint type and drop height, and the behaviour of test specimens is interpreted
