this article considers the seismic behavior of beam-to-column joints in steel frames for different bolt arrangements by using of finite element modeling. as the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. four different specimens have been analyzed. these models had some differences such as bolt arrangement and the presence or a...

As the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. Four different specimens have been analyzed.

This paper examines the dowel-bearing strength of laminated flattened-bamboo lumber (LFBL) perpendicular to grain under influence arrangement method, bolt diameter, and specimen size in accordance with ASTM D5764-97a. There were 360 specimens tested total. As a result test results, it was demonstrated that method flattened bamboo panels significantly affected LFBL. In two groups (bolt direction...

This study investigates the shear capacity of aluminum alloy honeycomb sandwich plates connected by high-strength, ordinary, or self-tapping bolts. For that purpose, experimental tests and finite elements are carried out. The failure of a high-strength bolt connector is driven by bending deformations developed in the bolt that deform connection plate and pad openings. In the case of ordinary bo...

An experimental study is presented on the effects of bolt-hole clearance on the load distribution in multi-bolt composite joints. Single-shear, three-bolt joints were studied. The specimens were manufactured from graphite/epoxy HTA/6376, with quasi-isotropic lay-ups. Protruding head bolts of 8 mm diameter and torqued to finger-tight conditions were used. Different combinations of clearance were...

In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...
