RISAn Analytical Investigation of the Topographic Amplification Effects of Slopes under Seismic Loads
Publisher: ASCE
Abstract: In this paper, an analytical approach is proposed to investigate the topographic amplification effects of slopes under seismic loads. The method of region decomposition and matching was adopted to decompose the whole ...
Cyclic Behavior of Central Columns in Subway Stations Subjected to Highly Variable Axial Compression Ratio
Publisher: American Society of Civil Engineers
Abstract: The failure mode of concrete columns in subway stations during seismic events can be affected by the dynamic fluctuation of the axial forces. This study conducted quasi-static tests with bidirectional loading on three ...
Enhancing the High-Temperature Fracture Toughness of Ultrahigh-Performance Concrete through Optimization of Ternary Cement Matrix and Plastic Fiber Geometric Properties
Publisher: American Society of Civil Engineers
Abstract: This study aims to enhance the high-temperature resistance of ultrahigh-performance concrete (UHPC) by optimizing the cement-fly ash-silica fume ternary cement matrix composition and the geometric characteristics of the ...

Effect of Dry-Wet Cycles on BFRP Bars and Modified Ceramsite Concrete in Marine Environments
Publisher: ASCE
Abstract: This study investigates the bonding behavior of modified ceramsite concrete (MLC) and basalt fiber-reinforced polymer (BFRP) bars exposed to dry-wet (D-W) cycles of simulated seawater using pull-out tests. Two types of ...
