Probing the Mechanics of Crumpled Graphene Membranes under Tensile Loading: An Experimental Study

Graphene is considered a promising material due to its unique electrical characteristics and excellent mechanical properties. These extraordinary properties make graphene a suitable material for applications like mechanical reinforcements, protective coatings, supercapacitors, sensors, etc. However, when trying to extract these properties...

Numerical investigation into the effects of corrosion on the shear performance of pretensioned bridge girders with cast-in-place slabs

Corrosion and shear cracking are frequently observed near supports of pretensioned bridge girders in coastal climates, so non-linear finite element analysis was used to study the effect of corrosion on shear performance in a real case study. Varying degrees of corrosion and various locations (top strands, bottom strands, vertical stirrups and...

Fracture simulation of a demountable steel-concrete bolted connector in push-out tests

Many bolted connectors were proposed for use in steel-concrete composite structures over the past few decades. This is because using bolted connectors could make the assembly and disassembly of steel-concrete composite structures more convenient and reusing the dismantled structural components could also improve structural sustainability. Lots...

Inspection and assessment of corrosion in pretensioned concrete bridge girders exposed to coastal climate

The most common methods for detecting chloride-induced corrosion in concrete bridges are half-cell potential (HCP) mapping, electrical resistivity (ER) measurements, and chloride concentration testing, combined with visual inspection and cover measurements. However, studies on corrosion detection in pretensioned structures are rare. To...

Durability of pretensioned concrete girders in coastal climate bridges: Basis for better maintenance and future design

This study was based on findings from the Norwegian Public Roads Administration's Bridge Management System and field investigations on corrosion damage in pretensioned Norwegian standard I-beam (NIB) girders in 227 coastal climate bridges. The main durability design parameters are summarized and related to regulations over the last 80 years....

Pretensioned cable-strut roof: A study with parametric design and optimisation

This thesis has been aiming to design a light-weight, structurally safe, and engineering practical pretensioned roof structure. Firstly literature study has been performed to gain insight about the application of tensegrities as roof structures. With some programming and scripting skills some special components based on the Grasshopper...
