Consistent with capacity design principles and requirements of ductile behavior, the 2005 AISC and 2001 CSA seismic design codes require that the intermediate horizontal boundary elements HBEs of steel plate shear walls SPSWs be designed to remain essentially elastic with the exception of plastic hinges at their ends when the infill plates fully yield under seismic loading. However, the unexpec...

This paper presents the behaviour and design procedure of bolted connections which tend to be sensitive block shear failure. The finite element method is employed examine research-oriented (RFEM) model validated with results experimental tests. used verify component-based FEM (CBFEM) model, combines analysis internal forces by plates, bolts welds component (CM). CBFEM verified an analytical sol...

This study uses a unique experimental system to explore the breakage of laboratory-grown, floating saline ice blocks under ice-to-ice contacts. topic is important understanding and modeling force transmission through rubble fields. In collection subjected compressive loading, transmitted via chains, their stability plays crucial role in ice-structure interaction processes. Peak loads are limite...

One of the most intricate problems in terminal ballistics is the physics underlying penetration and perforation. Several penetration modes are well identified, such as petalling, plugging, spall failure and fragmentation (Sedgwick, 1968). In most cases, the final target failure will combine those modes. Some of the failure modes can be due to brittle material behavior, but penetration of ductil...

Failure and fault slip in crystalline rocks is associated with dilation. When pore fluids are present drainage insufficient, dilation leads to pressure drops, which turn lead strengthening of the material. We conducted laboratory rock fracture experiments direct in-situ fluid measurements demonstrate that dynamic rupture propagation can be stabilised (i.e., become quasi-static) by such a dilata...
