Optimum Design of Plane Trusses Using Mathematical and Metaheuristic Algorithms on a Spreadsheet
(
Qatar University Press
, 2023 , Conference Paper)
Mathematical optimization refers to the process of finding the values of variables that maximize or minimize a function. Structural optimization is the process of designing a structure in such a way as to minimize its ...
Box Jacking Method Implementation in Rock for Mesaimeer Pedestrian Underpass Structure in Qatar
(
Qatar University Press
, 2023 , Conference Paper)
Mesaimeer pedestrian underpass is proposed under the live traffic of Sabah Al Ahmad Road, Doha, Qatar which consists of a four dual lane carriageway, in addition to diverge lanes, service road lanes and right turn lanes ...
Digital Twins in AEC Infrastructure and Building Management Systems
(
Qatar University Press
, 2023 , Conference Paper)
The current practice of Architecture, Engineering, and Construction (AEC) management systems relies on time-consuming, manual methods for data collection, analyzing, and decision-making. This affects the productivity of ...
Utilisation of Waste Plastics Admix with Laterite Soil for Production of Road Pavement Interlocking Blocks
(
Qatar University Press
, 2023 , Conference Paper)
Plastic wastes are non-biodegradable and hence pile up in refuse dumps and streets constituting an eyesore and menace to the environment. Some of them end up in drainages and waterways where they block water passages ...
Launching a 148m-Long Tunnel Boring Machine from a 15m-Inner Diameter Shaft
(
Qatar University Press
, 2023 , Conference Paper)
The city of Doha has grown and expanded rapidly in the last 20 years, but this growth has strained the country's infrastructure, including its aging sewerage system and treatment facilities. ASHGHAL has therefore launched ...
Exploring Crowd Management and Evacuation Strategies using Microscopic Pedestrian Simulation: A Case Study of Souq Waqif
(
Qatar University Press
, 2023 , Conference Paper)
Safe egress plans are critical for crowd evacuation at touristic attractions, particularly during special events, as visitors are often unaware of their options. Identification of bottlenecks in the walking spaces are vital ...
Hardened Properties of Self-Compacting Concrete Incorporating Recycled Granite Waste as Fine Aggregate
(
Qatar University Press
, 2023 , Conference Paper)
The present paper investigates the hardened properties of self-compacting concrete by reusing granite waste to replace natural fin aggregates. The reuse of solid wastes as powder or aggregates allows us to produce sustainable ...
Self-compacting Backfills using Fly Ash and Dredged Marine Sediments for Public Work Applications
(
Qatar University Press
, 2023 , Conference Paper)
Sediment accumulation at the bottom of ports disrupts maritime activities and disturbs the physicochemical balance of water bodies. In France, the maintenance of the 6500-kilometer long coastline would require the extraction ...
Planning and Implementing of Effective Enabling Works for a Successful TBM Tunnelling Project
(
Qatar University Press
, 2023 , Conference Paper)
The outfall tunnel, which forms part of the Musaimer Pump Station and Outfall project (MPSO), is a 10.2 km long subsea tunnel that extends from the south coast of Doha, starting onshore, and continues under the Arabian ...
Enhancing the Bond Durability of Basalt Fiber Reinforced Polymer Bars Using Basalt-Macro Fiber Reinforced Concrete
(
Qatar University Press
, 2023 , Conference Paper)
This paper presents a study about the bond durability of basalt fiber reinforced polymers (BFRP) bars embedded in concrete incorporating basalt macro fibers (BMF) when conditioned in harsh saline environment at 60 °C. A ...
