This paper investigates the seismic performance of Intermediate Moment-Resisting Steel Frame structures considering effects height and soil-structure interaction. For this purpose, three 3D 3, 6 9-story were designed using CSI ETABS software in accordance with ASCE7-16. Then 2D frames simulated by OpenSEES to account for nonlinearity material, plastic hinge elements used. The analyzed IDA metho...

The response of moment resisting frame structures to seismic excitation is strongly dependent on the ability of particular structural members to sustain relatively large inelastic deformations without significant degradation of lateral and axial load-carrying capacity. Conventional reinforced concrete frame structures are typically designed according to the strong column/weak beam concept, whic...

This research aims to investigate the extent that an incorrect assumption for soil type may endanger seismic safety of moment-resisting steel frame structures using probabilistic assessment. To this aim, first, a set were designed site class C. The examined 3-, 6-, and 9-storey frames according ASCE7-16. Then, assuming actual had been B, C, or D, vulnerability assessments performed OpenSees sof...

Abstract Currently, there is no “timber moment frame structural system,” as the basic glulam beam‐to‐column connections (usually represented by bolted with slotted‐in steel plates) offer limited rotational stiffness such that they are usually treated pin connections. This paper proposes an innovative type of moment‐resisting connection reinforced long rods screwheads (LSRSs) and self‐tapping sc...

The present study addresses optimal design of reinforced concrete (RC) columns based on equivalent equations considering deformability regulations of ACI318-14 under axial force and uniaxial bending moment. This study contrary to common approaches working with trial and error approach in design, at first presents an exact solution for intensity of longitudinal reinforcement in column section by...

Abstract. In the recent past, authors proposed a new steel device devoted to representing an innovative moment resisting connection for frame elements called LRPD (Limited Resistance Plastic Device). It is element characterized by symmetry with respect three orthogonal barycentric planes and constituted sequence of portions abrupt cross section changes, each one identifies suitably designed geo...

One of the methods for retrofitting reinforced concrete moment frames is the use of steel braces. In this research, the seismic performance of a double-skinned concrete framing system reinforced with two concentric (CBF) and eccentric (EBF) steel bracing, was investigated under seven near-fault earthquake records of varying intensity. For this purpose, two ten-story concrete frames with five sp...
