This paper explores the use of Carbon fiber reinforced polymer (CFRP) material for strengthening of steel bridges. The research work includes an experimental program to study the effectiveness of using very small diameter CFRP strands, configured in a sheet format, for strengthening of steel structures. The experimental program includes scaled steel-concrete composite beams strengthened with th...

Plates of austenitic stainless steel are often used in orthopedic surgery for fixing ends of the broken bones and for repairing fractures. The paper analyzes a premature breakage of six plates for fixing broken bones with different patients during their recovery. Each plate's breakage can induce serious aftermaths such as a new surgery, unexpected undesired complications and a prolonged healing...

This paper presents the development of a CFRP system for strengthening and repair of steel bridges and structures. The research program included development of the strengthening system, investigation of the behavior of strengthened bridges and special structures, and detailing requirements. Based on the research comprehensive guidelines including structural detailing are provided. This paper de...

In general, plates are classified as thick when the minimum dimension to thickness ratio (b/h) is less than 10, thin b/h ranges from 10 about 100, provided that plate maximum deflection (w/h) 0.2, and membranes approaches 100 w/h ≥ 0.2. Thick develop internal stress resultants governed by three-dimensio...

Abstract: In this study, carried out by fka, the hood of the VW Golf V is taken as an example to analyze the potential of a hybrid construction of aluminum and steel. Structural stiffness, oil canning and dent resistance behavior are analyzed using Abaqus/Standard. With the objective of reducing the total hood weight, the performance of the hood is compared to reference values of the series pro...

This paper presents the application of three main Artificial Neural Networks (ANNs) in damage detection of steel bridges. This method has the ability to indicate damage in structural elements due to a localized change of stiffness called damage zone. The changes in structural response is used to identify the states of structural damage. To circumvent the difficulty arising from the non-linear n...

steel 2205 is one of the most famous duplex stainless steels. the microstructure of this steel composed of ferrite and austenite in similar amount. therefore, in order to improve mechanical properties through microstructure, thermo mechanical processes such as controlled hot rolling and forging should be applied. it is not possible to employ the usual heat treatment. it shows the importance of ...

A mapping between the CIMsteel Integration Standards (CIS/2) and the Industry Foundation Classes (IFC) product data models for structural steel has been developed. The development of the mapping takes a pragmatic approach through a manual inspection of both schemas to see which entities and attributes correspond to each other. In some cases there is a direct one-to-one mapping between CIS/2 and...
