Analysis of a reinforced concrete beam in torsion
Eight reinforced concrete beams with two different concrete strengths and four different schemes of reinforcing were tested to failure in pure torsion. SR⁻⁴ strain gages were used to measure the concrete strains at the surface of the test beams. A review of analytical and experimental studies in …

Strength and Performance of Steel Fiber Reinforced Concrete Post-Tensioned Flat Plates
… a one-third scale model steel fiber reinforced concrete post-tensioned flat plate. The specimen had nine 10ft x 10ft x 3in. bays along with a 2ft-6in. overhang. Distributed loading was applied with a whiffle tree loading system at each bay and overhang section. Throughout the test, crack widths, …

Application of New Materials and Innovative Detailing for Reinforced Concrete Structures
<p>Confinement enhances mechanical properties of concrete sections specifically its strain capacity thus results is higher displacement capacity for reinforced concrete members. Even though the behavior of concrete confined with external jackets has been extensively investigated in previous …

Top Strand Effect and Evaluation of Effective Prestress in Prestressed Concrete Beams
… on bond strength in pretensioned prestressed concrete members. The "top strand effect" was evaluated through transfer and development length tests of prestressed concrete beams. Eight beams were cast with normal orientation, while four beams were cast with inverted orientation so that a …

Zusammenwirken von Beton und Stahlprofil bei kammerbetonierten Verbundträgern
… structures consisting of structural steel and concrete maximize the advantages of the two components provided that there is sufficient shear connection. When high strength materials are applied, the positive effect becomes even more apparent. Today, using high strength materials and partially …

Einfluss der Bodenreaktionskraft beim Durchstanzen von Einzelfundamenten
… The results of five punching tests on reinforced concrete footings supported on soil are presented. The experimental results indicate that the angle of the shear failure plane is steeper than observed in punching tests on flat slabs. Since the beginning of the 20th century only few punching tests …

Study of Internal Strains Developed in Concrete Decks at Early Ages in Steel Continuous Bridges
… identified bridge deck cracking shortly after concrete decks are placed and prior to applying traffic loads. Previous researchers have confirmed improper construction practices and design methods can lead to deck cracking. Currently, many contractors throughout Arkansas are using continuous …
