The objectives of this investigation were to study the strength and behavior of slowly (statically) loaded reinforced concrete slab-column connections and to determine the effect of rapid (dynamic) loading on the strength and behavior by comparison with the static test results. Nineteen full-scale models of a connection and adjoining slab area, consisting of a simply supported slab 84 or 94 inches square and 6-1/2 inches thick loaded concentrically on a 10- or 20-inch-square stub column at the center of the slab, were tested. The main variables were the amounts of reinforcement in the slab (p = 0.75 and 1.50 percent), the column size, and the loading speed. Eight specimens were loaded to failure statically, two were subjected to a very rapidly applied load of short duration, and nine were loaded to failure by a rapidly applied load with a rise time chosen to represent the conditions in a blast-loaded structure. The static test results are compared with 12 shear strength prediction methods. Differences between the mechanism of shear failure in slabs and beams are examined. (Author).

Structures such as industrial facilities, military protective structures, and infrastructures. This study presents experimental investigation for strengthening RC slabs under impact loads using shear reinforcement. Slabs were strengthened against punching shear with two methods: using shear studs as shear reinforcement and using steel fiber reinforced concrete (SFRC) instead of plain concrete. Eight RC slabs with dimensions of 2150x2150x150 mm were tested. Four of the specimens, two identical pairs, were cast with shear studs around the point of impact. Remaining four specimens, again two identical pairs, were cast with 1% steel fibers. Pairs in each group contained two different levels of longitudinal reinforcement. For each pair, one specimen was tested under static loading, whereas its identical twin was tested under impact loads. Specimens were tested with a test setup that provides simply supported conditions. Support loads, displacements, accelerations, and strains on bars were measured during the tests. The study revealed that using shear studs and SFRC prevents brittle punching shear failure for both static and impact loading. Specimens with steel fibers reached the highest load carrying capacity for static test while specimens with shear reinforcement carried a smaller load for large deformations. Specimens with SFRC displayed a close to static behavior under impact loading, influenced only slightly by inertial forces due to impact. Specimens with shear studs were largely influenced by inertial forces and scabbing occurred at some areas. Specimens with steel fibers endured more impacts compared to control specimens and specimens with shear studs due to their higher energy dissipating capabilities.

At the time this study was initiated, civil defense planning in the United States called for the evacuation of nonessential personnel to safe host areas when a nuclear attack is probable, requiring the construction of blasts shelters to protect the keyworkers remaining in the risk areas. The placement of shear stirrups in the one-way reinforced concrete roof slabs of the shelters will contribute significantly to project costs. Ten one-way reinforced concrete slabs were statically and uniformly loaded with water pressure, primarily to investigate the effect of stirrups and stirrup details on the load-response behavior of the slabs. The slabs had clear spans of 24.0 inches, span to effective depth ratios of 12.4, tensile reinforcement of 0.75 percent, and concrete strengths of approximately 5,000 psi. The test series significantly increased the data base for uniformly loaded one-way slabs. Support rotations between 13.1 and 20.6 degrees were observed. A more ductile behavior was observed in slabs with construction details, implying better concrete confinement due to more confining steel (i.e., closely spaced stirrups, double-leg stirrups, and closely spaced principal reinforcing bars). The parameters investigated did not appear to have a significant effect on ultimate load capacity.

Unter "bewehrtem Beton" versteht man eine Kombination von Beton mit anderen, verstärkenden Materialien (meist Stahl). Aus Stahlbetonplatten werden nicht nur Häuser gebaut, sondern auch Straßen und Mauern. Bauingenieure müssen die Merkmale und Einsatzfelder dieser Werkstoffe kennen und Belastungsgrenzen abschätzen. Dieses Buch, das einzige seiner Art, dient Praktikern und Studenten der Bautechnik als kompetenter Begleiter. (01/00)

Design guides and manuals for blast-resistant reinforced concrete structures require the use of shear reinforcement (lacing bars or stirrups) to improve performance in the large-deflection region of response. It is generally known that the cost of using lacing reinforcement is considerably greater than that of using single-leg stirrups due to the more complicated fabrication and installation procedures. A thorough study of the role of shear reinforcement in structures designed to resist blast loadings or undergo large deflections has never been conducted. A better understanding of the effects of shear reinforcement on large deflection behavior win allow the designer to determine the benefits of using shear reinforcement and to determine which type is most desirable for the given structure. This capability will result in more efficient or effective designs as reflected by lower cost structures. Results of an experimental study comparing the effects of stirrups and lacing are presented.
