A new model, based on sound simple physical considerations, allowing the assessment of the capacity of concrete to carry concentrated loads without transverse reinforcement is presented with a view for its application to the practical case of plate anchored reinforcement bars.
Shear has been observed to be often the governing failure mode of RC cantilever deck slabs of bridges without shear reinforcement subjected to concentrated loads when tested under a quasi-static application of the load.
Reinforced concrete slabs without shear reinforcement subjected to concentrated loads near linear supports are usually designed or assessed in shear using design provisions that have been calibrated on the basis of tests on one-way slabs or beams with rectangular cross-section (slabs loaded over their full width).
(iii) In the concentrated regime, for a given polymer, the reinforcement amplitude can be tuned by the rigidity of the filler network, which directly depends on the particle particle interaction.
Three reinforced concrete slabs without shear reinforcement with dimensions of 1.50 × 1.50 × 0.23 m are subjected to cycles of a concentrated centric load with increasing peak values up to failure.
An effective strengthened-glass fabrication method was developed, which involves combined reinforcement incorporating ion exchange using dispersed concentrated potassium nitrate powder, followed by quenching at 15 K/s.
Interestingly, change of the sugar substrate to an unprocessed concentrated wheat straw hydrolyzate resulted in substantial (≥2-fold) reinforcement of the process intensification effect of the strain evolution.
The proposed DFH control strategies include unsymmetrical grouting for the whole roadway, re-design of the roof and ribs support, reinforcement of the weak zones, and release of the concentrated stress in the earlier stage.
In order to overcome these limitations, HA collagen scaffolds were prepared by compression molding HA reinforcements and paraffin microspheres within a suspension of concentrated collagen fibrils (∼180 mg/mL), cross-linking the collagen matrix, and leaching the paraffin porogen.
The following study analyzes the shear behavior of full-scale slabs without shear reinforcement (the design of slabs used in nuclear buildings) under a concentrated load near a linear support.
