Durability And Fatigue Behavior Of Cip Concrete Connections For Accelerated Bridge Construction, Peng Zhu
Durability And Fatigue Behavior Of Cip Concrete Connections For Accelerated Bridge Construction, Peng Zhu
Doctoral Dissertations
Continuous longitudinal and transverse U-bar joint connections between flanges of the decked bulb-Ts (DBTs) or between precast panels for accelerated bridge construction are investigated. The procedure for selecting durable closure pour (CP) materials for the connections is discussed firstly. The accelerated construction is quantified as two categories: overnight cure and 7-day cure of CP materials. Candidate materials are selected first based on literature review as well as tests of compressive strength and flow and workability. Then, performance criteria for selecting durable CP materials for both categories are developed based on durability tests of selected candidate materials. These durability tests include …
Development Of Innovative Load Transfer Mechanism To Reduce Hurricane-Induced Failures In New And Existing Residential Construction, Sheikh Saad Ahmed
Development Of Innovative Load Transfer Mechanism To Reduce Hurricane-Induced Failures In New And Existing Residential Construction, Sheikh Saad Ahmed
FIU Electronic Theses and Dissertations
Implicit in current design practice of minimum uplift capacity, is the assumption that the connection's capacity is proportional to the number of fasteners per connection joint. This assumption may overestimate the capacity of joints by a factor of two or more and maybe the cause of connection failures in extreme wind events. The current research serves to modify the current practice by proposing a realistic relationship between the number of fasteners and the capacity of the joint. The research is also aimed at further development of non-intrusive continuous load path (CLP) connection system using Glass Fiber Reinforced Polymer (GFRP) and …
Investigation Of The Behavior Of Open Cell Aluminum Foam, Patrick J. Veale
Investigation Of The Behavior Of Open Cell Aluminum Foam, Patrick J. Veale
Masters Theses 1911 - February 2014
The study investigates the behavior open cell aluminum foam in scenarios applicable to potential use in structural applications. Behavior was examined through mechanical testing, computer modeling and analytic expressions. Existing assumptions about the foam characteristics that define the elastic properties were expanded to include contributions of axial and shear deformations in addition to bending and were rewritten in terms of the axial and bending stiffness ratios of ligaments. Compressive and tensile tests were performed to gain a measure of the elastic properties of the foam as well as the behavior and failure mechanisms in both loading conditions. The materials used …
