Steel plate shear walls usually do not satisfy the strong-column weak-beam design criteria, leading to larger column sections. On other hand, rigid frame structures are typically constructed in low-rise mid-rise buildings built locations prone strong earthquakes due their high flexibility and cost-effective solutions. Overcoming these restrictions SPSW system, this paper is dedicated employing ...

In steel modular buildings, both inter- and intra-module connections can attract bending moment under the action of lateral loads. The is distributed in accordance with relative stiffness ratios among structural components hence should have sufficient flexural resistance to connecting members be classified as a rigid connection. Typically, (beam-column joints within module) are designed full-st...

This paper extends the Wittrick-Williams (W-W) algorithm for hybrid dynamic stiffness (DS) models connecting any combinations of line and point nodes. The principal novelties lie in development both DS formulation solution technique a sufficiently systematic general manner. parent structure is considered to be form two dimensional elements with nodes, which can connected rigid/spring supports/c...

An exact dynamic stiffness method is proposed for the free vibration analysis of multi-body systems consisting flexible beams and rigid bodies. The theory sufficiently general in that bodies can be any shape or size, but importantly, permits connections to number at arbitrary points oriented angles. For beam members, a range theories including Bernoulli-Euler Timoshenko are applied. assembly pr...

The paper deals with the preparation of an experiment semi-rigid timber connections using modern connectors Rothoblaas Alumidi. consists loading a bracket structural wood. This is attached to glue laminated beam Alumidi connector. There are few specimens, which will be examined. Each specimen differs in number and measurements beams. deformations connection itself, as well deformation measured ...

objectives : microbial leakage through the implant-abutment (i-a) interface results in bacterial colonization in two-piece implants. the aim of this study was to compare microleakage rates in three types of replace abutments namely snappy, goldadapt, and customized ceramic using radiotracing. materials and methods: three groups, one for each abutment type, of five implants and one positive and ...
