BLADE v.3.0 – SDOF Calculations and Contact Detonations
BLADE (Blast Load Assessment and Damage Evaluation) is a software tool that provides an approximate assessment of the damage level of structures and components under blast loading. It can analyse both structural elements (slabs, beams, columns) and building envelope elements (walls, windows, side panels). BLADE considers a wide range of materials, including various types of concrete, masonry, steel, and glass. The tool not only assesses the damage to structures, but also examines the potential impact of blasts on human bodies. It can predict the likelihood of injuries resulting from blast exposure, like ear drum rupture, lung damage, skull fracture and whole-body impact. More specifically, BLADE utilizes pressure-impulse (PI) curves to assess the level of damage a structure or component might sustain using user-defined combinations of explosive charge and distance. This report describes the principles behind extending the functionalities of the tool’s previous version. BLADE 3.0 allows for Single-Degree-of-Freedom (SDOF) calculations of PI curves for additional structures and components, specifically steel sections and Cross-Laminated Timber (CLT) components. Furthermore, a new feature has been introduced that allows users to evaluate damage to concrete slabs when exposed to contact detonations, incorporated in a new, user-friendly graphical user interface.
