This paper proposes a methodology framework for the reliability assessment of smart steel Moment Resisting Frame structures (MRFs) equipped with Nickle Titanium Shape Memory Alloy (NiTi SMA) connections subjected to blast loading. The is formulated based on two-step approach algorithm. In 1st Step, Monte Carlo Latin Hypercube Sampling Strategy simulation (MC-LHS) adapted generate uncertain para...

The main purpose of the present work is to investigate the impact of soil-structure interaction on performance-based design optimization of steel moment resisting frame (MRF) structures. To this end, the seismic performance of optimally designed MRFs with rigid supports is compared with that of the optimal designs with a flexible base in the context of performance-based design. Two efficient me...

Abstract This study presents the impact of near-field and far-field earthquakes on seismic design Intermediate Moment Resisting Frame (IMRF) Special (SMRF) structures through FEMA (Federal Emergency Management Agency) P695 methodology to highlight importance probabilistic collapse as well performance factors these structures. The purpose this is investigate steel intermediate special moment res...

Following the Northridge earthquake of 1994, a significant number of steel moment resisting structural systems were damaged. Several studies have been conducted to improve the seismic performance of steel structures and specially their beam-to-column connections. One of the proposed connections for special moment-resisting frames included AISC-358 is Kaiser bolted bracket moment connection, bri...

The proposal lateral load pattern for pushover analysis is given in two forms for symmetric concrete buildings: 1-(X/H)0.5 for low-rise and mid-rise buildings, 2- Sin(ΠX/H) for high-rise buildings. These two forms give more realistic results as compared to conventional load patterns such as triangular and uniform load patterns. The assumed buildings of 4, 8, 12, 16, 20 and 30 story concrete bui...

In the first part of current study, effectiveness transversal cross-section reduction method for RC beams in marginal areas (by means mechanical drilling) was validated. The said “encourages” formation plastic hinges at beam ends and, same time, allows taking into account bending stiffness slabs, which is exerted upon beams. these conditions, second research study (i.e., manuscript) highlights ...
