Strengthening The Reinforced Concrete Column With Cf Sheet, Florim Istrefi

UBT International Conference

Fiber reinforced polymer (FRP) composites (the combination of two or more materials). The strengthening of concrete members means using constructional measures to restore or improve their load-carrying capacity, serviceability, durability or fatigue strength.

The effects of strengthening measures can generally be described in quantitative terms and therefore analyzed numerically for reinforced concrete columns designed according to the earlier editions of DIN 1045, ACI Committee 440, 2002, there are some strengthening assignments that fall midway between redesign and sprayed concrete. It is for these projects that wrapping with fiber-reinforced materials is to be recommended. This method has already been used frequently …

Effect Of The Opening In Flat Slabs On Punching Shear Resistance According To En 1992-1-1:2004, Xhemshir Mulliqi

UBT International Conference

After the war in Kosovo is highlighted by the construction of reinforced concrete buildings with flat slabs with no beams and no enlarged column heads .These slabs are subjected to punching shear failure of slab-column connections. Load concentration around the column head generally leads to increased stresses which cannot be absorbed solely in thin slab thicknesses. The punching shear strength is an extremely significant parameter for the design of flat slabs. Solution of architecture often imposes the necessity of openings near the columns .In this paper will examine the effect of openings in different positions and with different dimensions in …

Prediction Of Punching Shear Capacity Of Two-Ways Frp Reinforced Concrete Slabs, Ilker Fatih Kara, Besian Sinani

UBT International Conference

An innovative solution to the corrosion problem is the use of fiber-reinforced polymer (FRP) as an alternative reinforcing material in concrete structures. In addition to the non corrodible nature of FRP materials, they also have a high strength-to-weight ratio that makes them attractive as reinforcement for concrete structures. Extensive research programs have been carried out to investigate the flexural behavior of concrete members reinforced with FRP reinforcement. On the other hand, the shear behavior of concrete members, especially punching shear of two-way slabs, reinforced with FRP bars has not yet been fully explored. The existing provisions for punching of slabs …

Network Forensic Investigation Of Internal Misuse/Crime In Saudi Arabia: A Hacking Case, Abdulrazaq Al-Murjan, Konstantinos Xynos

Annual ADFSL Conference on Digital Forensics, Security and Law

There are ad-hoc guidelines and a limited policy on computer incident response that does not include computer forensic preparation procedures (e.g. logging incidents). In addition, these guidelines do not consider the requirement of Islamic law for admissible evidence at an organisational level in Saudi Arabia. Network forensic investigation might breach the Saudi law if they follow ad-hoc or international digital forensic standards such as Association of Chief Police Officers (ACPO) guidelines. This might put the organisation in a costly situation when a malicious employee sues an Islamic court. This is because the law of Saudi Arabia is complying with Islamic …

Making Scholarly Activity Available To The Masses: The Scaffolding Of Scholarship Throughout The Undergraduate Curriculum, Michael Savarese, Trent R. Brown, Carolyn Culbertson, Anna Carlin

Florida Statewide Symposium: Best Practices in Undergraduate Research

Florida Gulf Coast University’s Quality Enhancement Plan (QEP) focuses on improving student critical thinking, information literacy, and written communication. Rather than developing these skills through traditional methods (e.g., through senior-level, independent research), these learning outcomes are practiced through scholarly experiences. Traditional undergraduate scholarship manifests itself through terminal, senior capstone or research experiences. These, because of the economy of scale, typically reach a minority of students, often just honors students or those approached by faculty mentors. At FGCU, however, scholarly experiences are a part of the curriculum throughout the program of study, and scaffolded to build greater depth and sophistication. Presented …

As a campus technology partner, the Hesburgh Libraries has begun planning for moving many of our services and infrastructure into the cloud. This initiative represents a radical …

Paper Session Ii: Computer Forensics Field Triage Process Model, Marcus K. Rogers, James Goldman, Rick Mislan, Timothy Wedge, Steve Debrota

Annual ADFSL Conference on Digital Forensics, Security and Law

With the proliferation of digital based evidence, the need for the timely identification, analysis and interpretation of digital evidence is becoming more crucial. In many investigations critical information is required while at the scene or within a short period of time - measured in hours as opposed to days. The traditional cyber forensics approach of seizing a system(s)/media, transporting it to the lab, making a forensic image(s), and then searching the entire system for potential evidence, is no longer appropriate in some circumstances. In cases such as child abductions, pedophiles, missing or exploited persons, time is of the essence. In …
