Flat Slabs in Eccentric Punching Shear: Experimental Database and Code Analysis

Eccentric punching shear can occur in concrete slab–column connections when the connection is subjected to shear and unbalanced moments. Unbalanced moments occur in all floor slabs at the edge and corner columns. As such, this problem is of practical relevance. However, most punching experiments in the literature deal with concentric punching...

Self-compacting high-performance fiber concrete for foundations: Part 1 -experimental verification and design considerations

An investigation is carried out into the applicability of self-compacting high-performance fiber concrete (HPFC) in foundations. A concrete mixture has been designed with a concrete cube strength of about 110 MPa. The concrete contains 60 kg/m³ steel fibers. The properties of the HPFC developed are very suitable for structural...

Self-compacting high-performance fiber concrete for foundations: Part 2—Fiber orientation and distribution

An investigation was executed into the applicability of self-compacting high performance fiber concrete in foundations. The applied concrete has a concrete cube strength of about 110 MPa and contains 60 kg/m³ hooked-end steel fibers (<i>L</i>_<i>F</i> = 30 mm, <i>D</i>_<i>F</i> = 0.38 mm). This publication consists...

The influence of moisture on the fracture behaviour of concrete loaded in dynamic tension

Dynamic tests demonstrate an extensive rate effect on the tensile strength as well as the post-peak behaviour beyond loading rates of about 50 GPa/s. One of the possible explanations for the observed rate effects on the fracture behaviour is enhanced resistance by moisture in the pores. To study the influence of the moisture content and pore...

Shear In Reinforced Concrete Slabs under Concentrated Loads close to Supports

The capacity of existing solid slab bridges in the Netherlands is under discussion for two reasons: 1) the increased traffic loads and volumes and 2) the fact that the majority of the existing bridges were built before 1976, and are thus reaching the end of their original life span. Upon assessment according to the governing codes, a large...
