The Effect of Surface Treatment of Basalt FRP Bars on the Shear Capacity of Oneway High-Strength Concrete Slabs
(
Qatar University Press
, 2023 , Conference Paper)
Corrosion is a common condition encountered by steel reinforcing bars which has a considerable negative impact on the structural integrity of concrete structures. Nowadays, applying anti-corrosive composite materials such ...
Bond Performance of Near-Surface Mounted BFRP Bars to Concrete
(
Qatar University Press
, 2023 , Conference Paper)
This paper presents the test results of a study on the bond performance of near-surface mounted (NSM) basalt fiber reinforced polymer (BFRP) bars to concrete. Twelve C-shape concrete specimens were tested under direct ...
A Comparison between Natural Pozzolana and Fly Ash Replacements on the Mechanical Properties of Concrete
(
Qatar University Press
, 2023 , Conference Paper)
This study investigates the effect of Natural Pozzolana (NP) and Fly Ash (FA) substitutes on concrete's mechanical and microstructural properties. Mixes containing 10 - 50 % cement substitute ratios were prepared and tested ...
Shear capacity of reinforced concrete deep beams using genetic algorithm
(
IOP Publishing Ltd
, 2020 , Conference Paper)
It is vital to understand the shear behaviour of reinforced concrete (RC) beams in order to avoid a catastrophic shear failure and design for ductile failure. However, due to the complexity in the shear failure mechanism ...
Experimental Investigation on the Flexural Capacity of Reinforced Concrete Beams with Treated Wastewater and Recycled Concrete Aggregates
(
Qatar University Press
, 2023 , Conference Paper)
Eco-friendly concrete is the most recommended sustainable option to reduce the excessive diminution of concrete natural resources and the high generation of greenhouse gas emissions. Therefore, the present study explores ...
Multimodal Transport For Smart Mobility in Emerging Cities: Case of Doha
(
Qatar University Press
, 2023 , Conference Paper)
A mobility focused smart city ensures an urban place that is shaped with latest innovations accentuating the overall well-being of its citizens. One of the significant aspects for assessing the Smart Mobility in an emerging ...
Data Interpretation Framework for Pile Thermal Integrity Testing
(
Qatar University Press
, 2023 , Conference Paper)
Given the inherent nature of how deep cast in-situ concrete foundations (piles and diaphragm walls) are constructed, evaluating their integrity is difficult. Several well-established methods for testing integrity have been ...
An Experimental Study of Two-way Ranging Optimization in UWB-based Simultaneous Localization and Wall-Mapping Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2022 , Conference Paper)
In this paper, we propose a new ultra-wideband (UWB)-based simultaneous localization and wall-mapping (SLAM) system, which adopts two-way ranging optimization on UWB anchor and tag nodes to track the target's real-time ...
Parametric Optimization of RC Beams Strengthened with FRCM Using FE Modelling and Response Surface Methodology
(
Qatar University Press
, 2023 , Conference Paper)
This study focuses on the numerical and statistical analyses to predict the mid-span moment capacity of RC beams strengthened with fabric reinforcement cementitious mortar (FRCM) laminate. A finite element model (FEM) has ...
The Use of Newly Developed Public Transportation System in Relation to People’s Thermal Perception of Outdoor Climate
(
Qatar University Press
, 2023 , Conference Paper)
In the past decade, Doha the capital city of Qatar has witnessed a massive shift in various fields including economy, education, and sports sector. This flux caused rapid population growth, and as a result have led to an ...
