This paper proposes a new relaxation model for steel tendons based on the equivalent creep coefficient to enable the accurate estimation of losses of cable forces. The equivalent creep coefficient works not only in the case of intrinsic relaxation but also under various boundary conditions. Based on
This article presents a study on the time-dependent behaviour of timber lightweight concrete composite floors. The option of using lightweight aggregates in concrete (LWAC), instead of normal weight aggregates, is the focus of this document. The load-slip behaviour of SFS-screwed joints in timber-L
