“…Because of this reason, numerous authors recently focused on the typical behaviour of simply supported glass plates subjected to explosions, providing interesting analytical formulations [1][2][3][4]. In [5,6], Wei and Dharani proposed a energy-based failure criterion for laminated glass panes subjected to blast loads, useful to predict the breakage of glass and the size of possible glass shards.…”

The paper analyzes the structural response of a high-level air blast loaded cable-supported façade. Since the glass panels and the cables present a typical brittle behavior and are subjected to elevated tensile stresses when a high-level explosion occurs, multiple dissipative devices are simultaneously introduced in the conventional glazing system to mitigate the maximum effects of the design blast wave. Dynamic analyses are performed using a sophisticated FE-model to describe accurately the response of the façade equipped by dissipative devices. Based on numerical results of previous contributions, viscoelastic spider connectors (VESCs) are introduced in the points of connection between glass panels and pretensioned cables, to replace "rigid" spider connectors commonly used in practice. At the same time, rigid-plastic frictional devices (RPDs) are installed at the top of the bearing cables to mitigate furthermore the bracing system. As a result, due to the combined use of VESCs and RPDs opportunely calibrated, the maximum tensile stresses in the glass panels and in the cables appear strongly reduced. In addition, the proposed devices do not trouble the aesthetics of such transparent structural systems. At last, simple design rules are presented to predict the response of cablesupported façades subjected to high-level dynamic loads and to preliminary estimate the mechanical parameters of combined VESCs and RPDs.

“…In accordance with popular blast-proof window designs specified by the Department of Defense UFC standard [8] and the ASTM standard [9], 3 mm thick glass panes are used in the LSG panel. It was proven by Wei et al that the most effective PVB thickness for blast mitigation is any number between 0.76 and 1.52 mm [10], resulting in a configuration with minimal thickness of 6.76 mm for the LSG panel.…”

An experimental study was conducted to investigate the performance of coated laminated safety glass panels under extreme temperatures and blast loading. Using a shock tube apparatus, specimens were evaluated under room temperature (25°C), low temperatures (-10 and 0°C), and high temperatures (50, 80, 110°C). Special environmental chambers were designed to heat up and cool down the panels to the required temperatures prior to blast loading. To mimic real applications for glass windows, specimens were clamped fully along the boundaries during experimentation. For each experiment, the incident and reflected shock wave pressure profiles were recorded using pressure transducers located on the muzzle of the shock tube. The real-time deformation of the sandwich specimens was recorded using two high-speed cameras. Three-dimensional digital image correlation was used to analyze the high-speed images and compute the full-field deformation, in-plane strains, and velocities during the blast-loading event. A post-mortem study of the sandwich specimen was performed to investigate the effectiveness of such materials under different temperatures to withstand these shock loads. Experiments were conducted to characterize the tensile behavior of the coating material as a function of temperature. The mechanisms of failure of the panel are in agreement with the failure mechanisms outlined for laminated safety glass (LSG) in previous studies. The results indicated that polymeric thin sheet coating on both outer faces of the LSG panel had major influence on mitigating the blast loading and containing the glass fragments. The composite panel showed great endurance during the blast loading for temperatures from 0 to 80°C. The failure of panel at -10°C is attributed to the glass transition of the coating material and the failure at 110°C is likely due tearing of the coating by the glass fragments.

“…The engineering computational model of air blast wave describes the rules of overpressure time with respect to the scaled distance after an explosion in air of equivalent TNT explosive. Based on analysis of experiments Friedlander [1] presented a strong practical model that the overpressure distribution in time at the positive phase zone is t and  are crucial in importance for describing overpressure distribution and many researchers persevered in improving the computational model of them [2][3][4][5][6][7][8][9][10].

“…So it is very difficult to determine widely adaptive equations for two of them just by analysis of experiments. Another problem is about the negative phase duration of air blast wave which is usually ignored in the previous studies but a number of researchers thought it is very important [8][9][10].…”

This paper presents a new engineering model on the air blast wave of TNT explosive. The model is built and the parameters are calibrated based on numerical simulated pressure time data of shock wave in air. The model describes the peak overpressure, impulse, typical time and attenuation coefficient of the shock wave with new computational equations. Comparison of pressure configuration for the scaled distance shows that the present engineering model can give consistent results with the numerical code and experiments.
