This study investigated the bending moment resistance of T-type, two-pin dowel joints connected with Scotch pine (Pinus slyvestris), beech (Fagus orientalis), chestnut (Castanea sativa) and oak (Quercus petraea) reinforced basalt glass woven fabric. The tests was carried out to determine joints. As a result test, it determined that one layer two surfaces reinforce fiber fabrics increases mechan...

Abstract In timber structures, knowledge of the splitting capacity beams loaded perpendicular to grain by dowel-type connections is primordial importance since brittle failure can occur. present work, single- and double-dowel-type following different edged distance arrangements are experimentally investigated derive behaviour Eucalyptus globulus L., which a hardwood species increasing interest ...

This paper summarizes a series of studies on the interface of fiber reinforced polymer laminates externally bonded to concrete substrates, carried out in the Laboratory of Engineering for Maintenance Systems, Hokkaido University. Appropriate test methods and bond models for shear bond, tensile bond and cleavage bond (bond under dowel force) are shown. Finally, experimental results on shear bond...

Dowel action is a well-known phenomenon in shear-related problems within structural concrete. The tests previously reported the literature to evaluate this contribution reinforced concrete beams without shear reinforcement were conducted any initial activation of tensile reinforcement. This paper presents experimental results dowel tests, performed novel test setup. setup reflects more realisti...

In contrast to nailed connections, little research has been done on bolted connections using a reversed cyclic loading scheme, although cyclic loading provides important information about energy absorption and damping properties, which is essential when analyzing seismic performance. Dowrick (1986) noted that the hysteretic characteristics for the primary connection of a subassembly govern its ...

Large multi-dowel connections can provide the strength and ductility required for large, highly-loaded timber structures, but their slip under load is not well understood. This an important gap in knowledge, because accumulated local displacements at represent a large part of deformation structure. The empirical relationships used design codes commonly scale single-dowel stiffness by number dow...

OBJECTIVE The aim of this study was to evaluate the effect of simulated periodontal ligament (SPDL) on custom cast dowel and core removal by ultrasonic vibration. MATERIAL AND METHODS Thirty-two human maxillary canines were included in resin cylinders with or without SPDL made from polyether impression material. In order to allow tensile testing, the roots included in resin cylinders with SPD...
