The frequent occurrence of major earthquakes highlights the structural challenges posed by long-period ground motions (LPGMs). This study investigates the seismic performance and resilience of five reinforced concrete (RC) columns with different high-strength steel bars under LPGM-induced cyclic loading. both experimentally and numerically. The results show that low-bond and debonded ... https://www.unitedssports.shop/product-category/ball-field-equipment-training-aids-team/
