In steel modular buildings, both inter- and intra-module connections can attract bending moment under the action of lateral loads. The is distributed in accordance with relative stiffness ratios among structural components hence should have sufficient flexural resistance to connecting members be classified as a rigid connection. Typically, (beam-column joints within module) are designed full-st...

Through numerical simulation, the blast-resistant performance of spray polyurea elastomer (SPUA) retrofitted concrete masonry unit (CMU) infill walls under far-range blast loading was studied. From an engineering perspective, effects boundary conditions and thickness a SPUA layer on enhancing resistance are discussed, SPUA-retrofitted grouted CMU compared. It is concluded that constraint anchor...

Abstract The paper shows the results of an experimental campaign aimed at investigating cyclic behavior a column-to-foundation joint for precast concrete elements. tested connection is realized adopting corrugated steel ducts embedded into foundation, in which column protruding rebars are anchored by grouting high performance mortar. program consists testing six full-scale reinforced square-sec...

A rockbolt acting in the rock mass is subjected to combined action of pull-out load and confining pressure, bond quality directly affects stability roadway cavern. Therefore, this study, pressure are applied grouted systems with defects by a numerical simulation method, detected ultrasonic guided waves study propagation law defective rockbolts under pressure. The results show that length locati...
