Lianne Brito

Lianne Brito was born and raised in La Habana, Cuba; she moved to the United States in 2010. She is pursuing a bachelor’s degree in Civil Engineering with an International Engineering Minor. Since she started as a freshman at the University of Central Florida with the LEARN program she developed a passion for research that has been growing since. Lianne also likes to be involved in many extracurricular activities as well such as being a STEM Ambassador for UCF and being part of the Executive Board for the SHPE Club as a Communications Chair. Lianne has conducted research in different fields within civil such as Construction, Structural and Geotechnical. She plans to obtain his Ph.D. in Civil Engineering and become a college professor.

Dynamic Centrifuge Modeling of Multiple Structures

Conducted at University of Colorado, Boulder part of Leadership Alliance summer research program

Mentors: : Dr. Shideh Dashti, Civil Engineering, University of Colorado, Boulder

Abstract: Seismic induced liquefaction has had enormous economic and social impact in cities where the soil is prone to liquefaction during seismic shaking. The response of structures to liquefaction is poorly understood. Consequently, it is difficult to determine how the liquefaction risk may be mitigated. Two different mitigation techniques were tested in the geotechnical centrifuge at the University of Colorado Boulder: 1) Densification of the soil underneath a structure; and (2) vertical prefabricated drains placed around the structure. The behavior of the structures with each mitigation technique is compared to the response of a similar structure without mitigation in terms of accelerations, settlements, foundation rotation, and strains imposed on structural elements. The experimental results presented in this study represent the importance of understanding better the different mitigation methods, which, on the one hand, may reduce soil settlements and, on the other hand, may increase ground shaking intensity that result in larger drifts and damage to the superstructure.

A Comparative Analysis of Grouted Splice Pre-Cast Columns vs. Standard Cast-in-Place Columns

Conducted at University of Central Florida part of the ICubed and FGLSAMP Program.

Mentors: : Dr. Kevin R. Mackie, Civil Engineering, University of Central Florida

Abstract: The study of precast concrete columns is essential to ensure safety in construction projects especially in high seismic zones. This investigation compares grouted splice pre-cast columns with standard cast-in-place columns typically found in seismic regions. In order to make these comparisons, half-size concrete column assemblies were fabricated and tested to failure. From this investigation data will be analyzed to draw conclusions about the benefits and potential downfalls of the grouted splice pre-cast columns when used for construction in seismic regions.

Using Triaxial Accelerometer and Gyroscope Sensors for Activity Recognition in Construction Sites

Conducted at University of Central Florida part of the LEARN Program

Mentors: : Dr. Reza Akhavian, Civil Engineering, University of Central Florida

Abstract: : In complex construction projects, acquiring knowledge on construction workers’ activities can help increase productivity and safety. The objective of this study is to utilize smartphone built-in accelerometers and gyroscope sensors in order to predict basic daily activities of construction workers such as hammering, drilling and shoveling.
