On Thermal Bowing Of Concrete Sandwich Wall Panels With Flexible Shear Connectors, Fray Pozo 2018 Utah State University

On Thermal Bowing Of Concrete Sandwich Wall Panels With Flexible Shear Connectors, Fray Pozo

All Graduate Theses and Dissertations

Thermal bowing, often referred as bulging or out-of-plane wall deflection, is a common issue on sandwich panel walls caused by a temperature differential between a building interior temperature and the environment. The stresses caused by temperature changes in concrete members are widely known in the practice of bridge design, but not on sandwich wall panels. For sandwich wall panel applications, it is common to have non-composite panels when the designer expects a high temperature gradient, what yields a less economical design, but reduces the bowing.

This project aimed to validate current assumptions regarding the heat flow in sandwich wall panels ...

An Experimental Test Bed For Developing High-Rate Structural Health Monitoring Methods, Bryan Joyce, Jacob Dodson, Simon Laflamme, Applied Research Associates

Civil, Construction and Environmental Engineering Publications

Complex, high-rate dynamic structures, such as hypersonic air vehicles, space structures, and weapon systems, require structural health monitoring (SHM) methods that can detect and characterize damage or a change in the system’s configuration on the order of microseconds. While high-rate SHM methods are an area of current research, there are no benchmark experiments for validating these algorithms. This paper outlines the design of an experimental test bed with user-selectable parameters that can change rapidly during the system’s response to external forces. The test bed consists of a cantilever beam with electronically detachable added masses and roller constrains that ...

Impact Of Owners’ Early Decisions On Project Performance And Dispute Occurrence In Public Highway Projects, Sogand Hasanzadeh, Behzad Esmaeili, Ghada M. Gad, Douglas D. Gransberg 2018 University of Nebraska - Lincoln

Impact Of Owners’ Early Decisions On Project Performance And Dispute Occurrence In Public Highway Projects, Sogand Hasanzadeh, Behzad Esmaeili, Ghada M. Gad, Douglas D. Gransberg

Civil, Construction and Environmental Engineering Publications

Disputes are common in the construction industry and lead to unnecessary cost and schedule overruns in projects. It is commonly believed that owners’ early decisions regarding the selection of delivery methods, procurement methods, and contract types affect the frequency and severity of project disputes; however, no previous study has empirically tested this hypothesis, particularly in highway public projects. Therefore, this study empirically investigated the effect of owners’ early decisions regarding project organization (i.e., delivery methods, procurement, and contract types) on performance measures (e.g., cost and schedule growth), specifically dispute performance metrics (e.g., frequency and severity of disputes ...

Social Contagion And Knowledge Acquisition In Construction Professional Service Firms, Oluwasegun O. Seriki, Roisin Murphy

Conference papers

The construction industry in Ireland, including professional service firms (PSF’s) operating therein, are undergoing a period of change and uncertainty driven by economic, demographic, political and technological factors. While considerable evidence exists demonstrating the relationship between environmental turbulence on organisational decision making, there remains a distinct lack of focus on behavioural patterns affecting decision-making process of construction firms. Social contagion (SC) theory asserts that the spread of ideas, attitudes, or behaviour patterns in a group is achieved through imitation and conformity, and is well established within social sciences research, and is increasingly being used to analyse organisational behaviour. However ...

An Embedded Sensory System For Worker Safety: Prototype Development And Evaluation, Chunhee Cho, Jee Woong Park

Civil & Environmental Engineering and Construction Faculty Publications

At a construction site, workers mainly rely on two senses, which are sight and sound, in order to perceive their physical surroundings. However, they are often hindered by the nature of most construction sites, which are usually dynamic, loud, and complicated. To overcome these challenges, this research explored a method using an embedded sensory system that might offer construction workers an artificial sensing ability to better perceive their surroundings. This study identified three parameters (i.e., intensity, signal length, and delay between consecutive pulses) needed for tactile-based signals for the construction workers to communicate quickly. We developed a prototype system ...

Aligning Construction Management Students' Minors With The Needs Of Industry Professionals, Isaac Alexis Maximov 2018 California Polytechnic State University, San Luis Obispo

Aligning Construction Management Students' Minors With The Needs Of Industry Professionals, Isaac Alexis Maximov

Construction Management

While in college, students will have to decide if they want to pursue a minor, in addition to their bachelor’s degree. To pursue a minor one has to take additional units, and one usually does this without any free electives, meaning their graduation date is most likely delayed. A minor, in theory, should provide additional benefits such as being more hirable and earning potential; however, in the construction industry, the minors construction management students are taking do not align with the needs of construction industry professionals in. And while most students believe having a minor will increase their salary ...
