Dynamic response of 3D printed beams with damping layers
(Massachusetts Institute of Technology, 2015)
3D printers are a relatively new technology and they could be used in the future to 3D print structural components in buildings or bridges. The main advantages of using 3D printing would be the optimization of the structures. ...
Assessment methodology for the environmental impact of bridges
(Massachusetts Institute of Technology, 2015)
Residential and commercial buildings and transportation represent 21% of the global greenhouse gas emissions in the world. In the United States, this percentile goes up to 38% of the greenhouse gas emissions of the country. ...
Implementation and evaluation of a recently developed rate-dependent effective stress soil model 'MIT-SR'
(Massachusetts Institute of Technology, 2016)
Reliable modeling of rate-dependency in soil properties remains a major challenge for accurate solutions of many geotechnical problems. Although there are many sources of experimental data concerning rate dependent properties ...
The Collier Memorial : a study of theory and construction
(Massachusetts Institute of Technology, 2015)
The Collier Memorial is a vaulted stone structure that was built on the campus of the Massachusetts Institute of Technology during the fall of 2014 and the spring of 2015. In the course of the last century, structural ...
Spatial distribution of dynamic amplification in progressive collapse analysis of building frames
(Massachusetts Institute of Technology, 2015)
The purpose to use Dynamic Application factor is to design and analysis the building and structures more efficient under the progressive collapse where one can only use only the Linear Static Analysis and times the results ...
Decision support for disruption management on high frequency transit lines
(Massachusetts Institute of Technology, 2015)
Incidents (due to equipment failures, passenger emergencies, infrastructure problems, human errors, etc.) routinely occur in metro systems. Such incidents can cause significant disruptions in service (from slowdown to full ...
Ancillary revenues in the airline industry : impacts on revenue management and distribution systems
(Massachusetts Institute of Technology, 2014)
Airlines have increasingly depended on ancillary revenue in response to rising fuel costs, de- creased yields, and an increasingly competitive environment. Estimates indicate that U.S. airlines collected over $8 billion ...
Modeling spread of word of mouth on Twitter
(Massachusetts Institute of Technology, 2015)
Twitter is a popular word-of-mouth microblogging and online social networking service. Our study investigates the diffusion pattern of the number of mentions, or the number of times a topic is mentioned on Twitter, in order ...
Integrating constructability into conceptual structural design and optimization
(Massachusetts Institute of Technology, 2015)
This thesis encourages interdisciplinary design exploration through consideration of constructability in conceptual structural design. Six new metrics are introduced to measure variability in structural components, impose ...
Bus passenger origin-destination estimation and travel behavior using automated data collection systems in London, UK
(Massachusetts Institute of Technology, 2010)
This research explores the application of archived data from Automatic Data Collection Systems (ADCS) to transportation planning with a focus on bus passenger Origin-Destination (OD) inferences at the bus-route level and ...
