Performance evaluation of innovative toggle brace damper for flexible structure seismic upgrade
(Massachusetts Institute of Technology, 2015)
Amplifying the motion of viscous dampers has been recognized as an effective solution to mitigate structural response to wind and seismic excitation. Motion amplification devices are designed to amplify a small interstory ...
Water quality modelling for recreational use in the Kallang River Basin, Singapore
(Massachusetts Institute of Technology, 2014)
Singapore's Active, Beautiful, and Clean Waters Programme (ABC) aims to provide functional use of its water bodies to the public. The Kallang River Basin, being part of the ABC Programme, will be used for recreational ...
Quantifying and integrating constructability into multi-objective steel floor framing design
(Massachusetts Institute of Technology, 2016)
This thesis explores the benefits and tradeoffs of two significant constructability considerations in structural steel floor framing design. A new constructability strategy combining both standardization and steel availability ...
Strength characterization of wood to wood connections using stress field analysis
(Massachusetts Institute of Technology, 2016)
Minimizing construction cost and material usage are two dominant aspects in structural design. As a building material, timber presents a cheap, renewable option. However, current practice favors steel connections for wood ...
Schematic design of distributed mass damping systems for tall buildings
(Massachusetts Institute of Technology, 2014)
As new high-rises grow taller and more slender, the design of tall buildings becomes heavily constrained by the control of lateral displacements and accelerations due to dynamic excitations. This has led to the development ...
Improving transportation access to the South Boston Seaport District
(Massachusetts Institute of Technology, 2014)
Boston's Seaport District comprises approximately 1,000 acres of mixed-use residential, commercial and industrial space, which fosters innovation, collaboration and entrepreneurship. Development in the area is occurring ...
Volumetric topology optimization under redundancy constraints
(Massachusetts Institute of Technology, 2016)
With ever-increasing pollution and scarcity of resources, structural optimization, the science of finding the optimal structural arrangements under equilibrium constraints, is becoming an increasing necessity in engineering ...
Form-finding of elastic gridshells
(Massachusetts Institute of Technology, 2016)
Elastic gridshells are obtained by elastic deformation of an initially flat grid into a three-dimensional shell-like geometry and were first implemented in architecture in the 1970's. Their mechanical behaviour, which ...
History and technology of Lemuel Chenoweth's covered bridges
(Massachusetts Institute of Technology, 2014)
Lemuel Chenoweth was a carpenter and bridge builder who played a key role in the development of the infrastructure of antebellum Virginia. Theodore Burr and Lewis Wernwag are among the designers who influenced the structure ...
Serviceability-based design of tall buildings subjected to vortex shedding
(Massachusetts Institute of Technology, 2015)
With the increasing rate of population, there is an increase in demand for housing for people and their families. Due to the limited amount of land space, one of the most viable and feasible solutions is increase the number ...
