Linking Geospatial Engineering Into Collaborative Multidisciplinary Bim Projects - An Educational Perspective, Avril Behan, Helen Murray, Jonathan Argue, Ronan Hogan, Audrey Martin, Pat O'Sullivan, Robert Moore, Malachy Mathews

Conference papers

This paper describes the background to and execution of a postgraduate project undertaken by students on DIT's MSc in Geospatial Engineering (GeoEng) in support of a project on level 2 BIM being undertaken by students on the MSc in applied Building Information Modelling & Management (aBIMM) around the retrofit of and new build extension to the Grangegorman Clock Tower Building. In support of this requirement, an external and internal survey of the existing structure and its surrounding topography was required. The aBIMM students and staff acted as the Design Team who subcontracted the Geo Eng group who were organised into …

A Review Of Approaches To Solving The Problem Of Bim Search: Towards Intelligence-Assisted Design, Hamed Khademi, Avril Behan

Conference papers

Due to the growing adoption of BIM and the rising popularity of cloud computing, BIM models are increasingly stored in central cloud repositories or Common Data Environments. Effective management and exploitation of these models creates the requirement for BIM retrieval systems. Thus far, the BIM industry has utilized general-purpose, text-based search techniques that operate on BIM metadata. This paper highlights the need for a domain-specific BIM search engine and reviews various approaches to address the problem of BIM search. Three main approaches were identified as context-, geometry-, and content-based BIM retrieval. For a comprehensive BIM retrieval system, all three approaches …

Extending Time Series Forecasting Methods Using Functional Principal Components Analysis, Isaac Michael Wagner-Muns

Masters Theses

"Traffic volume forecasts are used by many transportation analysis and management systems to better characterize and react to fluctuating traffic patterns. Most current forecasting methods do not take advantage of the underlying functional characteristics of the time series to make predictions. This paper presents a methodology that uses Functional Principal Components Analysis (FPCA) to create smooth and differentiable daily traffic forecasts. The methodology is validated with a data set of 1,813 days of 15 minute aggregated traffic volume time series. Both the FPCA based forecasts and the associated prediction intervals outperform traditional Seasonal Autoregressive Integrated Moving Average (SARIMA) based methods"--Abstract, …

Development Of Structural-Functional Integrated Energy Storage Concrete With Innovative Macro-Encapsulated Pcm By Hollow Steel Ball, Hongzhi Cui, Waiching Tang, Qinghua Qin, Feng Xing, Wenyu Liao, Haibo Wen

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Phase change materials (PCMs) have great potential for applications in energy efficient buildings. In this study, an innovative method of macro-encapsulation of PCM using hollow steel balls (HSB) was developed and the thermal and mechanical performance of PCM-HSB concrete was examined. The macro-encapsulation system (PCM-HSB) was attached with a metal clamp (c) for better mechanical interlocking with the mortar matrix. The latent heat of PCM-HSB-c that can be acquired is approximately 153.1 J/g, which can be considered to rank highly among PCM composites. According to the self-designed thermal performance evaluation, the PCM–HSB-c concrete panel is capable of reducing and deferring …

Development Of Vegetation-Pervious Concrete In Grid Beam System For Soil Slope Protection, Xiaohua Bao, Wenyu Liao, Zhijun Dong, Shanyong Wang, Waiching Tang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

One of the most efficient and environmentally friendly methods for preventing a landslide on a slope is to vegetate it. Vegetation-pervious concretes have a promising potential for soil protection. In this study, the vegetation-pervious concrete with low alkalinity was developed and studied. Combined with a grid beam structure system, the stability and strength between the vegetation-pervious concrete and base soil are believed to be enhanced effectively. For improving plant adaptability, the alkalinity of concrete can be decreased innovatively by adding a self-designed admixture into the cement paste. The effects of the admixture content on alkalinity and compressive strength of the …

Prestressed Concrete Inverted Tee Beams With Cfrp For Building Structures, Herish A. Hussein, Zia Razzaq

Civil & Environmental Engineering Faculty Publications

Presented herein is the outcome of a study of prestressed concrete inverted tee beams with carbon fiber reinforced polymer (CFRP) sheets for possible use in building structures. To determine an effective approach for the use of CFRP, nine different retrofitting schemes are investigated for a prestressed beam under quasi-static distributed load to increase flexural strength. The theoretical analysis is based on coupling moment-curvature relations with a central finitedifference formulation. Three different thicknesses of CFRP sheets are studied in both tension and compression and effective retrofitting schemes are identified.

Cfrp Retrofitting Schemes For Prestressed Concrete Box Beams For Highway Bridges, Hussein A. Herish, Zia Razzaq

Civil & Environmental Engineering Faculty Publications

This paper investigates various retrofitting schemes for a prestressed concrete box beam using carbon fiber reinforced polymer (CFRP) sheets with the goal of increasing flexural strength. A simply-supported box beam is studied with a constant uniformly distributed load and three gradually increasing concentrated loads proportional to HS20 truck loading of the Association of State Highway and Transportation Officials (AASHTO). Various retrofitting schemes are considered each with single, double, and triple CFRP sheets, respectively, installed in high compression and tension regions. Cross-sectional nonlinear moment-curvature relations are developed and coupled with a finite-difference solution algorithm to predict load-deflection relations for both retrofitted …
