Triaxial shake table testing of an integrated low‐damage building system

Earthquake Engineering &Structural Dynamics, Volume 52, Issue 10, Page 2983-3007, August 2023., 2023
Abstract Lessons from recent earthquakes have provided a tough reality check of the traditional seismic design approach and technologies, highlighting the urgent need for a paradigm shift of performance‐based design criteria and objectives toward low‐damage design philosophy and technologies for the whole building system.

PRIMARY AND SECONDARY REINFORCEMENTS IN REINFORCED CONCRETE CORBELS

Journal of Civil Engineering and Management, 2013
The study is concerned with normal-strength concrete corbels. 30 such corbels were studied by finite element modelling and the variables considered include ratios of primary and secondary reinforcement, type of applied loading, vertical or horizontal.

Load‐bearing capacity of Gerber saddles in existing bridge girders by different levels of numerical analysis

Structural Concrete, Volume 24, Issue 1, Page 211-226, February 2023., 2023
Abstract This paper numerically investigates three typologies of Gerber saddle in existing ordinary and post‐tensioned girder concrete bridges. The main goals of this work concern the evaluation of the effective load‐bearing capacity of Gerber saddles, and the identification of weak points (i.e., lack of enough diagonal reinforcement, loss of ...

Finite Element Analysis of a Reinforced Concrete Dapped‐End Beam under the Effects of Impact Velocity and Dapped‐End Beam Cross‐Section Geometry

Advances in Materials Science and Engineering, Volume 2023, Issue 1, 2023., 2023
This study focuses on the behavior of a three‐dimensional reinforced concrete dapped‐end beam subjected to the effects of impact velocity and dapped‐end beam cross‐section geometry by numerical simulation using ABAQUS (V6.14) software under a constant impact load. The finite element software ABAQUS is utilized to simulate and analyze the drop impact to

Experimental Study on Two‐Step Concrete Corbels with Several Interface Conditions

Advances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023
Corbels are usually used in precast concrete structures for beam–column connections and are common in industrial structures to support crane girders and may be required in new alteration works. To overcome the difficulty of casting columns with corbels, especially in precast concrete industry, columns are sometimes cast without their corbels, and then ...

Statistical analysis on metric and geometric features of dolmens in the Gor river megalithic landscape (Granada, Andalusia, Spain)

Archaeometry, Volume 64, Issue 4, Page 815-832, August 2022., 2022
Abstract The construction of dolmens took place in Europe from the Neolithic to the Early Bronze Age (fifth millennium BC–second millennium BC) and had a rapid development along the Atlantic façade, with an important focus in Andalusia. Within this area, the megalithic necropolises located in the banks of the Gor River (Granada, Andalusia, Spain) are ...

Investigation on Strengthening Approaches Adopted for Poorly Detailed RC Corbels

Fibers, 2017
Poor detailing of the position of bearing pad over reinforced concrete (RC) corbel may lead to premature failure, which is undesired and structurally vulnerable.

Reinforced concrete corbels strengthened with external prestressing [PDF]

Revista IBRACON de Estruturas e Materiais, 2019
Abstract Reinforced concrete structures may demand, throughout their lifetime, the increase of the capacity load due to eventual changes in the load configuration. In this context, corbels could be considered structural elements which present great challenges for installing strengthening solutions.
