Abstract

"Since 2012, the subsequent reinforcement of reinforced concrete components with bonded reinforcement has been regulated in a separate guideline. This includes the dimensioning of the adhesively bonded strips made of carbon fiber reinforced plastic (CFRP), which, in addition to the complex iterative bending design, have a very complex bonding behavior. For this purpose, the German Committee for Structural Concrete developed a model for the verification based on experimental evaluations, in which the occurring tensile forces are partly transferred into the component via intermediate elements (partial distances between flexural cracks). Simultaneously, simplified but more inaccurate verification formats were made available to reduce the complexity of the verification. For an early assessment of the use of bonded CFRP strips, different tools have been developed in this paper for reinforced concrete components with a rectangular cross-section depending on the different verification formats. For this purpose, the design parameters were considered separately for pure bending strength and bonding behavior. For a simple calculation, tables for the design with dimensionless coefficients were obtained by analogy with the reinforced concrete construction, with which the required cross-section area for the CFRP strips can be determined by means of a limited stretching from the simplified verification of the flexural load bearing capacity. For a more economical solution, the more precise verification of the force transmission on the intermediate elements was configured in an Excel workbook, because this results in an extraordinary iterative calculation effort."

Abstract

"The need for an immediate, transparent and sustainable dissemination of current research has become a prerequisite for the further development of science today. Making research results freely available online as Open Access is considered to achieve the widest possible dissemination worldwide. Everyone can access anywhere Open Access publications without any restrictions or paywalls. Meanwhile more and more academic institutions and universities have already started their own presses to publish books Open Access. In the present manual a sustainable and ideal workflow for producing and publishing academic books is presented. That workflow enables universities to publish their publications both as Open Access and printed books in a state-of-theart way and without any restrictions regarding the license, the variety of formats, print run etc. As proof of concepts we have processed different use cases which demonstrates the current status of the technically and economically possibilities in the publishing sector. Furthermore, data on time, costs and personnel resources were determined, which can be used by other universities and academic institutions to indicate the necessary investments for founding and operation of their own Open Access university presses."
