Ground vibration is one of the undesirable results of blasting operations. Different methods have been proposed to predict and control ground vibration that is caused by blasting. These methods can be classified as laboratory studies, fieldwork and numerical modeling. Among these methods, numerical modeling is the one which saves time and cuts costs since it takes into account the basic princip...

Research was conducted to analytically investigate the blast-response and behavior of multihazard-resistant bridge piers having circular-shaped, concrete-filled steel tube (CFST) columns. Two different analysis methods, namely a single-degree-of-freedom (SDOF) dynamic analysis and a fiber-based dynamic analysis, were used for this purpose and calibrated with the maximum residual deformations ob...

Mount Coonowrin located in the Sunshine Coast hinterland north of Brisbane, is one of a scattered group of peaks and hills that constitute the Glasshouse Mountains and which is protected within the Glasshouse Mountains National Park. Concern about visitor safety in relation to rockfalls on the mountain were supported by the results of two geotechnical studies and led to the closure of this sect...

Drill and blast is the most cost-effective excavation method for underground construction, however, vibration noise, induced by blasting, have been consistently reported as problems. Cut blasting has widely employed to reduce blast-induced problems during excavation. We propose that large hole boring using state-of-the-art MSP (Multi-setting smart-investigation of ground pre-large boring) machi...

The service environment of civil air defense engineering structures is relatively harsh, and the corrosion steel bars main reason for reducing durability concrete in engineering. A hybrid FRP–steel-reinforced (hybrid-RC) structure has excellent durability. Therefore, it a good choice to apply hybrid-RC structures. In order study blast resistance structures, close contact experiments were carrie...

The need to design blast resistant civilian structures has arisen due to aggressor attacks on many civilian structures around the world. Achieving vibration and wave attenuation with locally resonant metamaterials has attracted a great deal of consideration due to their frequency dependent negative effective mass density. In this paper, metaconcrete, a new material with exceptional properties i...

The paper defines and describes blast waves, their interaction with a structure and its subsequent response. Explosions generate blast waves, which need not be due to explosives. A blast wave consists of two parts: a shock wave and a blast wind. The paper explains how shock waves are formed and their basic properties.The physics of blast waves is non-linear and therefore non-intuitive. To under...
