Determination of probabilistic models for resistance of Missouri bridges
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] As part of an overall project sponsored by MoDOT to calibrate the live load factor considering the typical bridge configurations in Missouri and ...
Simplified model for reinforced concrete beams under catenary action
(University of Missouri--Columbia, 2010)
The purpose of this research is to develop simplified models to predict the load displacement behavior for any reinforced concrete beam on the basis of material, geometric, and design parameters. The proposed simplified ...
Evaluation of alternative resistance mechanisms for progressive collapse
(University of Missouri--Columbia, 2011)
The purpose of this research is to better understand the collapse resistance mechanisms of reinforced concrete buildings. Currently, resisting progressive collapse is generally outside the design considerations for ordinary ...
Evaluation of the effects of in-plane lateral restraint and reinforcement ratio on the punching capacity of flat slab column specimens
(University of Missouri--Columbia, 2013)
Localized damage to certain structural members in a building can trigger a chain reaction which results in a partial or complete collapse of the building. A collapse of this nature is called a progressive collapse and has ...
Simplified analysis to predict the behavior of RC beams under collapse
(University of Missouri--Columbia, 2012)
The behavior of beams under progressive collapse plays an important role in resisting the collapse. This research addresses the complicated behavior of beams under collapse. The goal of this research is to provide an ...
Evaluation of a mechanical anchoring system to improve performance of carbon fiber reinforced polymer mitigated concrete slabs under close in blasts
(University of Missouri--Columbia, 2013)
Recent events, including the bombings of the Murrah Building in Oklahoma City in 1995 and the World Trade Center in New York in 2001, have drawn attention to the fact that explosive loads can cause extreme damage and loss ...
Evaluation of tensile and compressive membrane action in isolated slab column specimen
(University of Missouri--Columbia, 2012)
Older flat-plate buildings are susceptible to progressive collapse in which the failure of one slab-column connection can propagate to other connections and cause a full collapse of the building. The most common mechanism ...
Evaluation of post punching capacity of flat plates under progressive collapse
(University of Missouri--Columbia, 2017)
This research investigates the post-punching resistance of flat-plate buildings without continuous bottom reinforcement. An overview on both the historical development of the analytical theories of punching mechanisms and ...
Ultrasonic measurement of stress in steel and concrete
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Advancements in ultrasonic technology may lead to the ability to directly determine stress (strain) in steel and concrete members through measurement ...
Dynamic capacity of isolated slab column specimens
(University of Missouri--Columbia, 2015)
Localized damage, particularly in flat plate structures, can cause a chain reaction of subsequent failures resulting in failure of a large portion or even the entire structure. This type of failure is known as a progressive ...
Experimental and analytical evaluation of disproportionate collapse flat-plate buildings
(University of Missouri--Columbia, 2015)
Reinforced concrete flat plate buildings without continuous integrity reinforcement may be vulnerable to disproportionate collapse if a supporting structural member was lost in an abnormal event. This research forces on ...
Evaluation of finger plate and flat plate expansion devices
(University of Missouri--Columbia, 2016)
The objective of this project was to learn the causes of premature deterioration of MoDOT finger plate and flat plate expansion devices under high traffic volumes and use that information to design new Load and Resistance ...
Investigation of the effects of dynamic loads on reinforced concrete flat-plate buildings under collapse scenarios
(University of Missouri--Columbia, 2018)
During the initial stages of a collapse, failure of the initiating member (i.e. column loss) can cause a dynamic load redistribution in the surrounding members. The ability of the structure to withstand these dynamically ...
Dynamic increase factor in reinforced concrete frames under disproportionate collapse
(University of Missouri--Columbia, 2017)
Under a disproportionate collapse, the sudden loss of a support causes a dynamic response that can amplify the internal forces in the surrounding members and lead to significant global damage. This study considered a ...
Evaluation of stress in concrete using ultrasonic waves
(University of Missouri--Columbia, 2018)
This research investigates the use of ultrasonic waves to evaluate the stress and damage in concrete. Tests were conducted on 6 in. x 6 in. x 12 in. plain concrete specimens (f'c = 6,000psi) at different loading stages ...
Experimental and analytical investigation of localization and post-peak behavior of steel members in tension
(University of Missouri--Columbia, 2019)
Accurate simulation of extreme limit states in structures subjected to abnormal loads, earthquake, or blast requires detailed understanding of their post-peak behavior. In steel structures, these extreme-limit states are ...
