Behavior Of Double-Sided Concrete Corbels Reinforced With Glass-Fiber Reinforced Polymer Bars, Ayman Farid Abu Obaida Nov 2016

Behavior Of Double-Sided Concrete Corbels Reinforced With Glass-Fiber Reinforced Polymer Bars, Ayman Farid Abu Obaida

Theses

Steel reinforced concrete members with small shear span-to-effective depth ratios (a/d), such as corbels; have many classical applications, mostly in tall building, precast structures, factory buildings, bridges, and foundations. Despite extended research works on the performance of such members, little information is available on the performance of these members when reinforced totally with internal fiber reinforced polymer (FRP) bars. The use of FRP bars in reinforcing concrete members would eliminate corrosion problems thus increasing the service life of the structure. This thesis aims at investigating the shear strength of double-sided concrete corbels reinforced with glass-fiber reinforced polymer (GFRP) bars. The …


Performance Of Continuous Concrete Slabs Reinforced With Hybrid Steel-Basalt Bars, Mohammad Sohayeb Akiel Nov 2016

Performance Of Continuous Concrete Slabs Reinforced With Hybrid Steel-Basalt Bars, Mohammad Sohayeb Akiel

Theses

Continuous steel-reinforced concrete structures are vulnerable to corrosion

Damage when exposed to harsh environment. Although replacing conventional steel entirely with basalt fiber-reinforced polymer (BFRP) bars can eliminate corrosion problems, the lower modulus of elasticity of BFRP would reduce serviceability of the structure. The use of hybrid steel-BFRP bars rather than BFRP bars only has a potential to improve the serviceability of continuous concrete

Structures without reducing the deformation capacity. Through experimental testing and numerical simulation, this work aims to examine the structural behavior of two-span concrete specimens internally reinforced with BFRP or hybrid steel-BFRP bars.

A total of 12 two-span …


Recycling Ceramic Waste Powder And Its Usage As An Alternative Ingredient In Concrete, Dima Mamoun Kanaan May 2016

Recycling Ceramic Waste Powder And Its Usage As An Alternative Ingredient In Concrete, Dima Mamoun Kanaan

Theses

Green environment is a challenging concern to accomplish in today’s world. This could be accomplished through an effective and beneficial recycling system through reusing solid waste materials. The study and exploration of alternative ingredients for concrete-making industry started more than five decades ago. Concrete that contains solid waste is referred to as “Green” concrete. Ceramic tiles are widely used in most structures; its production creates waste powder. Using ceramic waste powder (CWP) as an ingredient to partially replace cement in concrete will have a positive and progressive environmental impact in addition will help reserve natural resources. In this study, CWP …
