Energy absorption capacities of reinforced concrete (RC) structural members depend on the level of ductility which is described in various ways. These include curva-ture, rotational, and displacement ductility (Cihanli and Arslan 2009). In order to provide a consistent level of minimum flexural ductility, an upper limit is generally set DVWLocal Reinforcement for Timber Joints Journal of They must have satisfactory strength and stiffness together with reasonable ductility and energy absorption, particularly if designed for use in seismic areas. In joints made with dowels, these requirements may more easily be met if the timber is reinforced locally in the area of the joints and use is made of a hollow cross section in place of

Addition of fibers make the material to fail in a fairly ductile manner in compression (compared with material with no fiber) as well as providing ductility and energy absorption in tension. In the recent decades, UHPC has been used in some small-scale applications while it has the potential to be used in larger scales to build sustainable and Experimental and numerical investigation on the axial May 18, 2020 · Non-linear finite element analysis of axially loaded SIFCON columns has been done by using ABAQUS computer program. Analytical predictions of load carrying capacity, axial displacement, ductility and energy absorption capacity are compared with experimentally observed results of SIFCON columns, and the results shown a good agreement between them.
Mar 01, 1997 · In the former case, the energy absorption characteristics of the foam were severely limited due to the inherent lack of tensile ductility. In the latter case, the absence of a failure mechanism led to arbitrary measures of energy absorption that were not indicative of true material properties.
