Evaluation of tensile and compressive membrane action in isolated slab column specimen
(University of Missouri--Columbia, 2012)
-plates is known as punching shear, when inclined shear cracks propagate through the depth of the slab and cause a conical failure around the column. Alternative resistance mechanisms such as compressive and tensile membrane action may enhance the strength...
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 redistributed loads...
Evaluation of alternative resistance mechanisms for progressive collapse
(University of Missouri--Columbia, 2011)
of three quarter scale two bay by two story frames. The column between the two bays was removed to simulate a collapse scenario. The design of the three frames consisted of discontinuous reinforcement, continuous reinforcement, and infill walls placed...
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 ...
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 ...
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 ...
