In progressive collapse events initiated by explosive threats, damage to some connections from blast loading of the structure is likely. In this paper, the results from ten tests of blast-damaged and undamaged beam-to-column connections are examined. An evaluation procedure leading to comparisons of performance based on rotational capacity of both blast damaged and undamaged capacity is presented.
The U.S. Army Engineering and Support Center, Huntsville is actively involved in the location and removal of buried unexploded munitions at formerly used defense sites (FUDS). In some cases the munitions are liquid filled which may indicate hazardous chemical agents. A critical parameter for chemical warfare material (CWM) safety siting is the downwind hazard in the event of an accidental detonation. A environmental steel arch vapor containment structure (VCS) over ...
Prediction of concrete structure spall and breach as generated by tactical weapons ranging in size from small mortars up to large aircraft bombs in size has traditionally been accomplished through the use of empirically generated prediction curves and algorithms based on data fits to those curves. Past attempts in generating these curves have resulted in less than satisfactory results when scaled thickness [T/W(exp 1/3)] and scaled distance [R/W(exp 1/3)] only ...
A new aircraft shelter design is to be used in the construction of shelters throughout Norway. The new shelter is called the third generation Norwegian/U.S. shelter due to structural characteristics common to both the third-generation Norwegian shelter and the third-generation U.S. shelter. Since test data for debris and blast hazards do not exist for this new shelter configuration, NATO has recommended using current aircraft shelter siting criteria to establish safe ...
