The license number required for the installation can be found on the back of the CD case. Customers with a network license will have to update their installation of the license manager in addition. We wish you the best of success with the new program functionalities. Sincerely yours, InfoGraph Ingenieurgesellschaft für graphisch unterstützte Datenverarbeitung mbH Attachment: One program CD and one short description per license. For network installations, only one CD per network hardlock is provided. Titelbild: 'Kaisersteg' Berlin, Germany. Courtesy of Krone Hamann Reinke Ingenieurbüro GmbH, Berlin, Germany. InfoCAD 14 Update Information News in InfoCAD 14 The following chapters provide you with the latest information on the InfoCAD program system and the most important changes with respect to the previous version 13 from May 2013. General • The analysis settings for the concrete construction checks have been revised. The operating logic of the check boxes have changed. • For the reinforcement representation the base reinforcement specified in the section can be subtracted. This is especially useful for the recalculation of structures. • Two new docking windows 'Layer' and 'Partial view' were added. They can be activated via the view menu and can be used during the work on the structure. • For model faces, partial views divided into planes and storeys can automatically be created. • In the data base cross-section numbers can be changed separately or in groups. • The representation mode 'Section color' can now be used for model objects. • The import of IFC files has been enhanced. • In model objects existing partial views can now also be preset for the elements. • The state of the option 'multiple' of the copy function is retained. • Load cases and combinations without any content can exist. • When combining the support reactions now also the support deformations are taken into account. 1 InfoCAD 14 Update Information Polygon Sections • In polygon sections the effective flange width can be defined. The selected areas are not taken into account for the calculation of the centroid coordinates and the bending moments of inert. Mindlin-Reissner Area Elements • A new option of the calculation settings allows using of area elements with an approach based on the Mindlin-Reissner plate theory. Buckling Eigenmodes • For the calculation of buckling eigenmodes a new method of calculation has been implemented. Nonlinear Structural Analysis • For the nonlinear analysis of area and solid elements an additional yield criterion according to 'Rankine' has been implemented. 2 InfoCAD 14 Update Information EN 1992-1-1 and National Annexes The design has been adapted to the national annex for Germany from April 2013 and supplemented with the following features: • When checking the crack width the decisive action combination can now be chosen freely. This allows e.g. to take the WU guideline into consideration. • The punching shear check has been supplemented with the design for diagonal reinforcing steel. • In the punching shear check for foundation slabs the resistance without punching shear reinforcement is now calculated according to Equation (6.50). • The punching shear checks for foundation slabs according to DIN EN 1992-1-1 are now conducted as per Chapter 6.4.4(2) of the standard in accordance with the commented version of September 2013. EN 1995-1-1 and National Annexes The design of timber structures has been adapted to the national annex for Germany from August 2013 and to the new product standard EN 14080:2013-08 for glue-laminated timber. In detail the following changes resulted from this: • The material type GL36 from the replaced EN 1194:1999 has been removed. • The new material types GL20, GL22, GL26 and GL30 according to EN 14080:2013 have been added. • The shear strength of glue-laminated timber has been changed to fvk = 3.5 according to DIN EN 1995-1-1/NA:2013. • The increase of the bending strength of gluelaminated timber as per Equation (3.2) is only applied for bending stress perpendicular to the smaller dimension according to DIN EN 1995-11/NA:2013. 3 InfoCAD 14 Update Information DIN EN 1992-2 The checks have been revised for the application of the recalculation guideline for road bridges. In detail the following application rules according to level 2 can now be used: • Safety and combination coefficients for actions acc. to Table 10.8 and Chapter 12.3.2. • Partial safety coefficients for construction materials acc. to Chapter 12.3.3. • Limitation of the concrete strut angle for lateral forces acc. to Chapter 12.4.3.3, Equation (12.11). • Selection of a constant concrete strut inclination for torsion according to Chapter 12.4.3.4(2). • Determination of a weighted lever arm z for prestressed cross-sections acc. to Equation (12.12). • Consideration of reduced requirements for the crack width limitation acc. to Chapter 12.6(2). • Reduction of the scattering coefficients for the prestressing force acc. to Chapter 12.5.3(1). Prestressing • A reduction factor of prestress for the robustness check of area elements has been implemented. • The tendon group and prestressing force tables can now be copied to the Windows clipboard for further processing. • A prestressing system with the SIA 262 certification has been added. SIA 262:2013 The design according to SIA 262 was adapted to the new edition 2013 of the standard. Simultaneously, the following features were added: • Checks against fatigue. • Serviceability checks. • Prestressing with and without bond for all components made of concrete. 4 InfoCAD 14 Update Information DIN 4227 The prestressed concrete checks have been fundamentally revised and supplemented in regard to the recalculation of existing road bridges. Basically the following changes resulted from this: • All calculations can now also be made for design objects and e.g. allow the check of solid elements conforming to the standard, for example. • In case of prestressed compound sections the tendon type 'mixed' is now also supported. • If the effective width is defined at the polygon section, it is decisive for the cross-section values. An additional full polygon is not necessary. • The cross-section options for averaging the shear stresses from lateral force and for the limitation of shear stresses from torsion are now taken into account for all checks. • The check listing has been restructured and provided with bookmarks. As a result, the access to listing contents has been considerably improved. • The single design has been supplemented. Structural analysis for fire scenarios • The structure analysis is now also available for area elements. • An external fire curve and a fire curve according to the ZTV-ING Guideline were added to the list of thermal actions. • For the calculation of the cross-section temperatures a new method for mesh generation has been developed. 5 • InfoGraph GmbH Kackertstraße 10 52072 Aachen, Germany Tel. +49-241-889980 Fax +49-241-8899888 E-Mail: [email protected] www.infograph.de 2
