Combining fiber with concrete mixes has become essential and its widespread use improves the strength of structural elements. This research conducted an experiment into performance flat slabs without a square opening using four types (hooked-end, straight, corrugated steel polyolefin fiber) to gain better understanding how variance type shape effects flexural behaviors two-way slabs. The test p...

This paper discusses the use of fracture mechanics for the microstructure tailoring of a fiber reinforced Engineered Cementitious Composite (ECC) to achieve extreme tensile ductility at the composite scale. It demonstrates that fracture mechanics applied to control fracture phenomena at the micro and meso material scales can lead to suppression of fracture failure at the macro structural scale....

Cracking of the concrete cover due to corrosion is defined as the serviceability limit state of reinforced concrete structures. This study evaluated the influence of a mineral admixture i.e. nano wollastonite on corrosion performance and serviceability of reinforced concrete structures by performing an accelerated corrosion test on ten reinforced concrete beams under a sustained load. To do so,...

this study evaluates two different types of techniques for concrete hollow-block sections reinforced with traditional steel rebars and wire meshes, and compares their structural behaviour to that of an ordinary reinforced concrete beam section. the comparisons are based on the responses both before and after they were repaired with glass fibre reinforced polymers (gfrp). the specimens were subj...

High-strength concrete is a material often used in the construction of high rise buildings. In the case of unexpected fire, the building concrete elements such as columns, slab and walls will be subjected to extreme temperatures. In order to assess the performance of high-rise reinforced concrete members it is important to understand the changes in the concrete properties due to extreme tempera...

Minimising carbon emissions from the building construction industry is of paramount importance in present context due to rising concerns climate change. This paper explores potential minimising embodied reinforced concrete flat slabs by parametrically varying slab thickness, grade concrete, column spacing, size, and reinforcement details. A parametric design algorithm was developed generate a r...
