Seismic evaluation of composite moment frames subjected to near-fault ground motions

open access: yesResults in Engineering, 2023
This paper investigates the seismic behavior of composite special moment frames (CSMF) under near-fault ground motions. For this purpose, two factors, response modification and deflection amplification are chosen.

Investigating effects of boundary conditions on the evaluation of R-factor of un-braced steel frames

open access: yesHBRC Journal, 2017
Design of Structures to resist seismic load depends on the theory of dissipation in elastic of energy that already exists in response modification factor “R-factor”.

System overstrength factor induced by interaction between structural reinforced concrete walls, floors and gravity frames: Analytical formulation

open access: yesBulletin of the New Zealand Society for Earthquake Engineering, 2022
In multi-storey structural wall buildings, the structural walls are required to resist additional shear force due to their interactions with the floors and gravity-resisting system, which is not fully catered for in current seismic design provisions and ...

Assessing Seismic Performance of the Elliptic Braced Moment Resisting Frame through Pushover Method [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering, 2019
The seismic performance of elliptic braced moment resisting frame (ELBRF) is assessed here and is found that the structural behavior is improved and is of free of architectural space.

MITIGATION OF ADDITIONAL OVERDESIGN IN PORTLAND CEMENT CONCRETE BY OPTIMIZING THE CEMENTITIOUS MATERIALS CONTENT

open access: yesMix Sustentável, 2022
More cement does not necessarily make better concrete or expedite construction schedules. In contrast, concrete with lower cementitious content can reach sufficient strength on time to avoid construction delays and last longer.

Effect of Degradation on Collapse Margin Ratio of Steel Moment Frames [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering, 2019
Although several studies have investigated the effect of degradation on the behavior of structures, inspections on collapse margin ratios are rare in the literature.

Study on overstrength and ductility of reinforced concrete building with different infill through nonlinear analysis

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2021
The building structure with infill wall shows higher global stiffness along with the uncertain behaviour during 2015 Gorkha earthquake. It significantly increased the collapse rate of structures during earthquakes.

Shake table investigations on code non-compliant reinforced concrete frames

open access: yesAlexandria Engineering Journal, 2020
Shake-table tests were performed on a code conforming and four non-compliant 1:3 reduced scale two-story RC frames. The models were subjected to 1994 Northridge earthquake acceleration time history, linearly scaled to multiple levels for studying the ...

Redundancy Factors for the Seismic Design of Ductile Reinforced Concrete Chevron Braced Frames

open access: yesLatin American Journal of Solids and Structures
In this paper the authors summarize the results of a study devoted to assess, using nonlinear static analyses, the impact of increasing the structural redundancy in ductile moment-resisting reinforced concrete concentric braced frames structures (RC ...

Failure Analysis of a Concrete Anchor under Severe Seismic Action

open access: yesApplied Sciences, 2021
We explored the usage of a response modification factor and overstrength factor for analyzing brittle or ductile failure of anchor system. Parametric studies on the tension and shear behaviors of anchor systems were compared in terms of elastic and ...
