Experimental and numerical investigations on methods for improving impact performance of precast segmental bridge piers

Precast segmental bridge piers (PSBPs) are increasingly used in accelerated bridge construction. However, segmental joints and bottom segments are more vulnerable to severe damage under impact loads. This study experimentally and numerically investigates three retrofitting method...

Thermal, mechanical, and energy-saving performance of capric acid-myristic acid/expanded perlite phase-change concrete for building envelopes

Phase-change concrete (PCC) can improve the heat-storage capacity of cement-based materials, but PCM incorporation often compromises mechanical performance. This study prepared PCC using capric acid-myristic acid (CA-MA) impregnated expanded perlite as a shape-stabilized PCM aggr...
