Experimental Study On Local Bond Stress-Slip Relationship In Self-Compacting Concrete, Marian Sabau, Ioan Pop, Traian Onet

Marian Sabau

This paper summarizes the results of an experimental study on local bond stress-slip relationship of deformed reinforcing bars embedded in self-compacting concrete, considering the effect of concrete confinement by transverse reinforcement. In this study were cast 104 specimens by using self-compacting concrete and vibrated concrete. Pull-out tests were performed on deformed bars with short anchorage length (ld ≤ 5∅). The parameters analyzed were the concrete type, the confining reinforcement, the bar diameter and the anchorage length of bar. The results of this study showed that the ultimate bond strength was higher for self-compacting concrete compared to vibrated concrete, and the slip ...

Measuring Building Substructures: Solutions To ‘First Year’ Introductory Level Examination Questions, Tony Cunningham

Other Resources

The measurement of substructure works to simple domestic type buildings is a logical starting point for students to commence the process of taking-off building quantities. Substructure work is typically the first class of work to be explained in textbooks dealing with both construction technology and building measurement. However, substructure work is often one of the most challenging elements to measure. In this paper, the author demonstrates the process of measuring basic substructure designs. The approach involves providing solutions to a sample of four Irish Department of Education Technological Certificate: Builders’ Quantities Intermediate Stage examinations. The intention is to demonstrate how ...

The Statistical Relevance And Effect Of Assuming Pessimistic Default Overall Thermal Transmittance Coefficients On Dwelling Energy Performance Certification Quality In Ireland, Ciara Ahern, Brian Norton, Bernard Enright 2016 DIT, Dublin Energy Lab

The Statistical Relevance And Effect Of Assuming Pessimistic Default Overall Thermal Transmittance Coefficients On Dwelling Energy Performance Certification Quality In Ireland, Ciara Ahern, Brian Norton, Bernard Enright

Articles

In the EU, Energy Performance Certificates (EPCs) are issued for dwellings whenever they are constructed, sold or leased. Where requiring data would be prohibitively costly, nationally applicable default-values for the thermal transmittance coefficients of the building envelope are employed. Use of such worst case default U-values ensure that a poor dwelling does not attain a better energy rating than is merited. In the absence of empirical data in Ireland thermal-default U-values, as in many other EU member states, are determined by the type and date of construction and then prevailing building codes. Using 463,582 dwellings representing 32% of the ...


De-Westernizing The Far East, Jericho K. Kakaio-Edwards 2016 University of San Francisco

De-Westernizing The Far East, Jericho K. Kakaio-Edwards

Undergraduate Honors Theses

Isolated by the Tibetan highlands which frame Yunnan’s northwest fringes, the ethnic minorities who call the region home live in rural settings ranging from rice-terraced fields to tropical forests; lifestyle unchanged for hundreds of years. However, with globalization causing an exposure to western standards of living, in conjunction with the country’s predisposition towards all things foreign, the people of Yunnan have begun forgoing generations of vernacular architecture in favor of modern materials and regionally defunct construction methods. Here, we will seek to address this foible of architectural development by offering theoretical construction methods for housing types found throughout ...


The Renaissance Of The Railway | Towards A Global High-Speed System, Xiaoyu Li 2016 Syracuse University

The Renaissance Of The Railway | Towards A Global High-Speed System, Xiaoyu Li

Architecture Senior Theses

The railway has shown its unique character as a mode of transportation since its invention in Europe during the Industrial Revolution. In the beginning, its carrying capacity made it stand out, transforming human behavior, and stimulating economic productivity. During the 20th century, air travel, the railways, and long-distance road networks have shared the burden of human transportation - in many countries the car and plane have won out. In recent decade, however, new interest in the railway's potential has been generated as a result of the emergence of new technologies like high-speed rail and the maglev system. Greater speeds are ...


Multidimensional Dialogue Through Architecture | An Exploration Of The Possible Dialogue Between Humans And Walls, Fengqi Li 2016 Syracuse University

Multidimensional Dialogue Through Architecture | An Exploration Of The Possible Dialogue Between Humans And Walls, Fengqi Li

Architecture Senior Theses

This thesis proposes that architectural design no longer has to be primarily static, but rather it can be dynamically responsive to multiple information streams and conditions.

Multidimensional Dialogue Through Architecture is developed from the understanding of human factors and ergonomics. The dispersed works on research and inference are different ways to explore the interaction between the discipline of architecture and the other fields, such as psychology, engineering, bio-mechanics, physiology, cognitive science, and anthropomorphic. Therefore, the purpose of this thesis is not to design a specific building that works perfectly in particular conditions but rather to use architectural elements to mediate ...


Subtraction | Construction In Reverse, Sherina S. Zhang 2016 Syracuse University

Subtraction | Construction In Reverse, Sherina S. Zhang

Architecture Senior Theses

The life of a building does not begin at the creation of the new; it starts with the subtraction of the old. As the pace of technological development accelerates, buildings are erected and demolished at an unprecedented rate. Cities use their urban artifacts like skyscrapers, to portray economic and political prowess. For example, the ghost cities of China are relics of a burst financial bubble while Venezuelan ruling party elites name business towers after themselves as a show of power and prosperity. Many parts of the world today are now overbuilt with artifacts that decline into obsolescence. Demolition procedures erase ...


Recognizing Construction Equipment Activities Using A Smartphone, David J. Engelhaupt 2016 University of Nebraska - Lincoln

Recognizing Construction Equipment Activities Using A Smartphone, David J. Engelhaupt

UCARE Research Products

The purpose of this research is to develop a smartphone based system to continually analyze construction equipment activity (e.g. a skid loader moving forward, side-ways, or raising its bucket) using a variety of different sensors and give feedback to the equipment operator or the supervisor. Such a system could detect inefficiencies in construction operations and provide valuable information to project managers.

The results have demonstrated that DTW is effective at identifying typical rotation patterns. It has been less effective for slow rotations over long duration or very fast rotations with short durations. The accuracy of DTW is improved when ...

A Review Of The Durability Aspects For Self-Compacting Concrete, Marian Sabau, Yamith Cantillo Mier, Traian Onet 2016 Universidad de la Costa

A Review Of The Durability Aspects For Self-Compacting Concrete, Marian Sabau, Yamith Cantillo Mier, Traian Onet

Marian Sabau

This article presents a literature review concerning the durability of self-compacting concrete (SCC), making a comparison between this new type of concrete and the vibrated concrete (VC). The degradation mechanisms that have been considered are: carbonation, chloride penetration, sulphate attack, frost durability and salt scaling, and fire resistance. The carbonation of SCC is not significantly deviating from the carbonation of VC. Cyclic wetting and drying in a chloride containing solution shows significantly lower chloride diffusion in SCC in comparison with VC. The initiation time for sulphate attack is prolonged in SCC compared with an equivalent VC due to a denser ...

Peering In: Improving Existing Buildings With Colorful Increments, Daire Heneghan

Master's Theses and Project Reports

Existing office buildings’ embodied energy, history and culture offer something a newly constructed building cannot. On the other hand, new office buildings’ adoption of new technologies and building philosophies offer a range of sustainable efficiencies previously unavailable. Combining these efficiencies with elements that embrace human diversity and well- being offer the opportunity to not only mend our existing buildings’ deteriorating physical bodies but aid in creating workplaces that promote good physical and mental health.

This project provides recommendation on how an existing high-rise commercial building can incorporate a number of incremental improvements that continually evolve to meet rapidly changing market ...

Better Infrastructure Procurement For Public Private Partnerships: An Australian Perspective, Michael Regan, Jim Smith, Peter Love

Jim Smith

Public private partnerships (PPP) are a method for the delivery of social and economic infrastructure services in over 80 countries worldwide. PPPs are a contractual arrangement between public and private entities through which the skills, assets and/or financial resources of both sectors are allocated in such a manner that provides optimal service delivery and good value to society. Central to the operation of public private partnerships is the systematic evaluation of the procurement options available to government, an output specification to encourage private design, risk transfer, construction and operational innovation, the detailed analysis of projects over their operational lifecycle ...
