Ductility enhancement of high performance cementitious composites and structures
(Massachusetts Institute of Technology, 2002)
High performance cementitious composites (HP2C) are a new generation of fiber reinforced cementitious composites (FRCC) with substantial improvements in mechanical behavior. The most important development in these HP2C ...
A constitutive model for the compression behavior of Old Alluvium
(Massachusetts Institute of Technology, 2008)
Old Alluvium is classified as a transported, in-situ weathered tropical soil, and represents a class of geomaterials that have a complex microstructure, including cemented aggregates at the meso-scale and groups of clay ...
Moisture degradation in FRP bonded concrete systems : an interface fracture approach
(Massachusetts Institute of Technology, 2005)
(cont.) characterization, and kink criterion implementation, form a synergistic analysis of the mechanistic debonding behavior affected by moisture. Results have shown that moisture affected debonding is a highly complex ...
Turbulent fluid jet excavation in cohesive soil : with particular application to jet grouting
(Massachusetts Institute of Technology, 2005)
This thesis reviews the jet grouting methodology, and the current state of practice and research. Current methods of prediction of jet grout diameters are highly empirical and site specific, and do not take into account ...
Acoustic data communication system for in-pipe wireless sensor networks
(Massachusetts Institute of Technology, 2006)
Sustainability of aging infrastructure is one of the greatest current civil engineering challenges, especially in the case of pipelines, where no direct access is available. Being simultaneously massive and distributed, ...
A consistent segment procedure for solution of 2D contact problems with large displacements
(Massachusetts Institute of Technology, 2006)
Solution of contact problems in solid mechanics using the finite element method is a challenging and non-trivial task. Stable and efficient contact algorithms are required for effective solution of general problems. In ...
Topography effects in the 1999 Athens earthquake : engineering issues in seismology
(Massachusetts Institute of Technology, 2004)
It is well known that irregular topography can substantially affect the amplitude and frequency characteristics of seismic motion. Macroseismic observations of destructive earthquakes often show higher damage intensity at ...
Earth pressure balance (EPB) shield tunneling in Bangkok : ground response and prediction of surface settlements using artificial neural networks
(Massachusetts Institute of Technology, 2002)
Although Earth Pressure Balance (EPB) shields have been used for several decades, very little information exists about the actual mechanisms of shield-ground interaction. The ground response mechanism induced by EPB tunneling ...
Airline fleet assignment and schedule design : integrated models and algorithms
(Massachusetts Institute of Technology, 2002)
In scheduled passenger air transportation, airline profitability is critically influenced by the airline's ability to construct flight schedules containing flights at desirable times in profitable markets. In this dissertation, ...
Gravity, capillary and dilational wave mode resonance at a visco-elastic two-fluid interface
(Massachusetts Institute of Technology, 2005)
(cont.) space corresponding to experimental conditions to thereby interpret the experimental results. We tested this method on noisy simulated data sets and then applied it to published experimental data sets. We designed ...
