• Damping Effects of the Passive Control Devices on Structural Vibration Control: TMD, TLC and TLCD for Varying Total Masses
Three passive vibration control devices that consist of Tuned Mass Damper, Tuned Liquid Damper and Tuned Liquid Column Damper are experimentally investigated in this study. A scaled three-story steel building structure coupled with each device is employed to evaluate the damping effect of each controller. This research experimentally presents that the mass and damping of passive devices are the key factors in structural vibration suppressing. Fast Fourier Transform, frequency modes and the total mass of devices are used to calculate the Power Spectral Density values. As a benchmark, a rigid mass has been attached in …show more content…

The initial time estimated to complete this project is four years.
2. Usage of sugarcane bagasse ash as a replacement to Portland cement in concrete
The target economic sectors of the proposed research are the sugar industry and the construction industry. The sugar industry will be directly affected, since the main goal of this research project is to develop a sugarcane bagasse ash-based product that can be used as an additive for concrete mixes. Due to the known properties and chemical composition of sugarcane bagasse, it is expected that this new product will be competitive with fly ash in terms of improving the properties of concrete mixes. The newly added economic value of bagasse ash may also make it economically advantageous to burning the entire stock of bagasse fiber for electricity production beyond the needs of the sugar mills. The local construction industry will be indirectly affected by the availability of an additive for concrete production with a lower cost and similar properties to fly ash. This new bagasse ash-based product is expected to reduce the construction costs of projects requiring large amounts of concrete (e.g., foundations, concrete bridges), thus, leading to a potential increase in the number of construction projects per year. The results of this research will have a significant impact on the economic development of US regions where the sugar industry is present, such as Florida, Texas, and Hawaii
