Bolted stiffened end-plate moment connections are one of the most usable used as a prequalified connection in special steel frames. According to AISC design code, this can be considered important parts resisting frames with enough bolt pretension levels. In paper, using three full-scale bolted designed according AISC, effects levels have been examined experimentally under SAC cyclic-loading pro...

Studies involving the mechanical properties of high-strength steel (HSS) at elevated temperatures have received considerable attention in recent years. However, current research on HSS high is lacking. As a result, design fire-protective structures with standards not sufficiently conservative or safe. This study investigates effect that ASTM A572 Gr. 50 and 60 steels. Reduction factors for yiel...

The intermodular connection between modules plays a vital role in the overall performance of modular structures. separation column and is possible due to absence links (welding or bolting) since limited space available modules. This study proposed self-locking joint be used steel structure, connecting columns with without need extra behavior subjected monotonic load was evaluated using finite e...

In this paper, an approach for conducting a Reliability-Based Design Optimization (RBDO) of truss structures with linked-discrete design variables is proposed. The sections of the truss members are selected from the AISC standard tables and thus the design variables that represent the properties of each section are linked. Latin hypercube sampling is used in the evaluation of the structural rel...

A plasticity model to predict the behavior of confined concrete is developed. The model is designed to implicitly account for the increase in strength and ductility due to confining a concrete member. The concrete model is implemented into a finite element (FE) model. By implicitly including the change in the strength and ductility in the material model, the confining material can be explicitly...

Composite concrete Filled Tubular Steel (CFT) members, which have excellent deformability due to the well-known confined and constrained interaction between steel tube concrete, largely been utilized as bridge piers or columns in high-rise buildings, resulting increased strength decreased column size. This study examined experimental performance of filled with reactive powder (RPC) under axial ...

Abstract Current structural codes for steel and stainless structures such as AISC 360-16, AISC 370-21, AS/NZS 4100 Eurocode 3 are based on the traditional two-step member-based design approach, in which internal actions first obtained from a analysis, usually elastic, strength of each member connection is subsequently checked using standard. However, most recent versions these standards already...

This paper describes the results of an experimental study to verify proposed design requirements for eccentrically braced frame links with hollow rectangular i.e., tubular cross sections. Twelve primary link specimens and two supplementary links that have different end connections are tested. Three cross sections and four normalized link lengths are considered. Two of the cross sections have we...
