Prestressed Concrete Design acc. to Eurocode 2 with RFEM With the RFEM add-on modules RF TENDON and RF-TENDON Design Dlubal can now offer two programs used to calculate prestressed concrete members with bonded post-tensioned concrete according to EN 1992-1-1 (concrete constructions) and EN 1992-2 (concrete bridges). RF-TENDON is the add-on module required to define tendons. With RF TENDON Design you perform the prestressed concrete design according to Eurocode 2 on the basis of the results calculated with RFEM and RF TENDON.
Working with RF-TENDON First one defines the structure, loads cases (load case for prestress without loading) and loads groups in RFEM. RF TENDON imports the RFEM data including cross-sections and materials. Then, one defines the tendons. The program database offers a variety of prestressing steels for selection. One can define straight and parabolic tendons automatically as well as manually. The tendon layout can be displayed in a 3D rendering overview. The load cases and groups are assigned to time intervals. Finally, the prestressing forces are calculated. They will be transferred automatically to RFEM where the internal forces are determined by calculation. In addition, RF-TENDON takes into account immediate loss of prestressing stress due to friction, anchorage set, relaxation and elastic deformation of concrete.
nal and shear reinforcements. One can just take advantage of the comfortable input tools provided by the program. RF-TENDON Design performs the required ultimate and serviceability limit state design according to EN 1992 1-1 for prestressed concrete members. Optionally, they can be calculated according to EN 1992-2. The design is carried out for axial force, biaxial bending, shear, torsion and combined internal forces. The program checks as well if the reinforcement rules according to Eurocode 2 are observed. The output is shown in clearly arranged results tables. Printout reports are generated in both add-on modules. The reports can be printed or exported in a RTF file.

Q Just like building physics, performance based building design was hardly an issue before the energy crisis of the 1970ies. With the need to upgrade energy efficiency, the interest in overall building performance grew. As the first of two volumes, this book applies the performance rationale, advanced in applied building physics, to the design and construction of buildings. After an overview of materials for thermal insulation, water proofing, air tightening and vapour tightening and a discussion on joints, building construction is analysed, starting with the excavations. Then foundations, below and on grade constructions, typical load bearing systems and floors pass the review to end with massive outer walls insulated at the inside and the outside and cavity walls. Most chapters build on a same scheme: overview, overall performance evaluation, design and construction. The book should be usable by undergraduates and graduates in architectural and building engineering, though also building engineers, who want to refresh their knowledge, may benefit. The level of discussion assumes the reader has a sound knowledge of building physics, along with a background in structural engineering, building materials and building construction.
