Heat of Hydration Thermal Performance and Flexural Capacity of Stainless-Steel Reinforced Concrete Sections
Stainless steel (SS) is increasingly used in the construction field due to its high strength and corrosion resistance. However, its coefficient of thermal expansion is different from that of concrete. This difference raises concerns about the potential for concrete cracking during the hydration …

The development of empirical chloride-induced corrosion rate prediction models for cracked and uncracked steel reinforced concrete structures in the marine tidal zone
… rate prediction models for cracked and uncracked reinforced concrete (RC) structures in the marine tidal exposure zone are proposed in this study. The data used to develop the models were obtained from parallel corrosion experiments carried out by exposing half of 210 beam specimens to accelerated …

Comparative study on the behaviour of concrete reinforced with FRP and steel singly reinforced beams
Maintenance and repair of concrete infrastructure account for a large amount of financial resources. This is due to the deterioration of reinforced concrete through the corrosion of steel reinforcement. The depassivation of the steel creates an environment prone to chloride ingress and carbonation. …

GFRP reinforced concrete : environmental and movement characteristics
… order to come over the problem of corrosion in steel reinforced concrete. Consequently, methods such as cathodic protection, epoxy coatings, concrete additives, etc., have been tried. Unfortunately, non of these methods has totally solved the corrosion problem. The outstanding characteristics of …

Behaviour of continuous concrete slabs reinforced with FRP bars. Experimental and computational investigations on the use of basalt and carbon fibre reinforced polymer bars in continuous concrete slabs.
… investigation on the application of basalt fibre reinforced polymer (BFRP) and carbon fibre reinforced polymer (CFRP) bars as longitudinal reinforcement for simple and continuous concrete slabs is presented. Eight continuously and four simply concrete slabs were constructed and tested to failure. …

Behaviour and analysis of a flexible concrete arch
The development of steel reinforced concrete in the early 20,h century led to a decline in masonry arch bridge building. Traditional masonry arch construction is time consuming and involves considerable formwork usually in the form of timber centring, as well as traditional skills. It is also …

Structural engineering model of irregular and efficient concrete beams: Application to topology optimized shapes and integrated textile reinforcement
Concrete remains one of the most widely used construction materials due to its strength, durability, and availability. However, it is responsible for a large share of the global carbon emissions. Within the 40% of the global emissions attributed to the building sector, 5-8% alone accounts for the …

The response of reinforced concrete slabs to hard missile impact
… the target parameters, the amount of reinforcing steel and maximum size of aggregate are not considered in the existing empirical formulae to determine critical perforation and scabbing velocities. The principle aim of the research reported in this thesis is, therefore, to find a term accounting …
