Experimental studies were conducted on 36 grouted splices to investigate their mechanical performance under four loading schemes: (1) incremental tensile loading, (2) repeated tensile loading, (3) cyclic loading at high stress, and (4) cyclic loading at large strain. Load-deformation responses of the grouted splices under cyclic loadings were featured with pinching effect and stiffness degradation compared to those responses under tensile loadings. The shape of the hysteresis loops of load-deformation curves was similar to that under incremental tensile loading. For the purpose of structural analysis, stress-strain relationships were presented for grouted splices under various loadings.Keywords: sleeve connector, grouted splice, cyclic loading, stress-strain relationship.

An asymmetric synthesis of 5-halomethyl
pyrazolines and isoxazolines
which bear a tertiary stereocenter by catalytic halocyclization of
β,γ-unsaturated hydrazones and ketoximes is described.
By using Brønsted acids of anionic chiral Co(III) complexes as
catalysts, a variety of chiral 5-halomethyl pyrazolines and isoxazolines
were obtained in good yields with high enantioselectivities (up to
99% yield, 97:3 er). Preliminary bioassay results indicated that several
isoxazoline derivatives exhibited significant antifungal activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
