Abstract: This paper discusses the nonlinear load-deformation behavior of coupling beam subassemblages in a new type of hybrid coupled wall system for seismic regions. Coupling of concrete walls is achieved by posttensioning steel ...

Abstract: This paper describes an analytical investigation of a new type of hybrid coupled wall system for seismic regions. Coupling of concrete walls is achieved by posttensioning steel beams to the walls using unbonded posttensioning ...

Abstract: This paper uses the experimental results presented in a companion paper to develop a seismic design approach for unbonded posttensioned hybrid coupled wall subassemblages. The test results are also used to verify and refine ...

Abstract: Eleven half-scale experiments were conducted to investigate the nonlinear reversed cyclic behavior of coupling beam subassemblages in a new type of hybrid coupled wall system for seismic regions. In this new system, coupling ...

Abstract: Hydraulic conductivity of polyanionic cellulose (PAC)–amended bentonite (PB) in calcium chloride (CaCl2) solutions was investigated to access its chemical compatibility in vertical cutoff walls application. PB was synthesized ...

Abstract: This study investigated the hydraulic conductivity and microscopic properties of two backfills, conventional sand/bentonite (SB) and sand/xanthan gum (XG)-amended bentonite/sand (XG-SB), for use in vertical cutoff walls ...
