Tower

Due to problem with instalation of HASP drivers on computers with Windows XP SP2 running AMD 64-bit processors, instalation routine has been modified - for more details click here.

This version also, contains fixes of couple minor problems reported from our users.

New features:

• Seismic walls - concrete design - multimodal seismic analysis - allowed reinforcement calculation with influences obtained with SRSS combination scheme.
• Concrete design - added information about number of stirrup cuttings into diagrams of adopted reinforcement.
• Concrete design - modified reinforcement marking and naming in beams with rotated section.
• Concrete design acc. MSZ codes - allowed analysis with buckling ignored.
• Prevented generation of multiple geometrically identical point or linear supports in command for exporting levels (ceilings).
• Prevented running of nonlinear analysis for models with moveable load.
• Solved problem with drawing of arrows in diagram of Nn.
• Corrected assigning of end releases for simple and nonlinear frames - in some circumstances end-releases were nonsymmetrical.

For network users, new installation feature added - for more details, click here. New features:

• Optimized drawing of arrows in surface and linear loads.
• Change in algorithm for multiple selection of slab releases.
• Modified calculation of extreme stress in beams for combinations and anvelope load-cases.
• Modified algorithm for load integration for beams calculated with 'Offset' option enabled.
• Changed tolerance range and default value for nonlinear analysis.
• Concrete design: modification of conditions for determination of imperfection (buckling) and enabled input of concrete reduction factor (SNIP)

New features:

• Concrete design acc. SNIP codes - changed algorithm for calculation of stirrups.
• Concrete design - in textual report added information about number of stirrup cuttings.
• Steel design acc. EC and SIA codes - changed algorithm for calculation of shearing area for I and [ sections; algorithm for stress control improved.
• TXT report - solved some minor problems with node numbering in reports for envelope load-cases.
• Finite elements mesh generation algorithm optimised and made less sensitive to tolerance problems.

New features:

• Calculation of reinforcement in seismic walls, export of project documentation into RTF file format, wizard for automatic conversion of surface loads into linear or concentrated loads over arbitrary selected grid of beams, calculation of resultant force for selected group of loads, calculation of thick plates with a new finite element. Number of allowable combination of load-cases is increased from 100 to 1024. Fixed problem with "AltGr" key.
• Currently, we are working on timber design module and addition for concrete design module - serviceability limit state, flections and cracking analysis.

New features:

• Nonlinear Analysis - Tension capable only and Pressure capable only truss elements.
• Report for cumulative mass participation factors used in seismic analysis.
• Concrete fissure calculation - SIA codes added.
• Concrete fissure calculation - defining Quasi - permanent loading scheme acc. EUROCODE.
• Report for complete loading scheme used for concrete design.
• Concrete design - Bulgarian localization of EUROCODE added.
• Steel design - SIA 263 code added.

New DEMO version of program Tower 5 is released. The DEMO program has the same functionality as professional version - structural analysis (theory I and II), stability analysis, modal analysis and seismic analysis - but it is limited to 300 node models. Concrete design, steel design and timber design are not available.

New features:

• Design of timber girders.
• Fissures and Flexions analysis (concrete design).
• Analysis according to second order Theory and calculation of critical load - Stability Analysis.
• Creation of tabelar reports for numerical results (text reports).
• Implemented algorithm for design of concrete plates considering "Mxy moment effect" recomended by Eurocode.
• Added Swiss code for multimodal seismic analysis.
• For users convenience, decreasing of diagrams and layouts of loads is now possible using key (SHIFT) besides ALT (for example ALT+F9 is the same as SHIFT+F9)
• IMPORTANT NOTICE:
• For some time, it is possible to get the illegal copies or cracks of our programs Tower 4, Planet and PanelPro. Those programs have protection system JUST PARTIALY removed so they "work" without presence of original dongle (hard-lock) but results of analysis are UNRELIABLE and INCORRECT and DIFFER from results obtained with original programs.
• We warn about risk of using those cracked programs.

New features:

• Improvement in presentation of axes in exported graphical blocks.
• Control of adopted reinforcement in seismic walls - more precise calculation.
• Smarter handling of intersected, unequal-typed releases in plates.
• Solved problems with deformations in thick plate elements.
• Changed condition for determination of beam joints suitable for joint offsets.
• In concrete design - changed algorithm for calculation of additional eccentricity for columns (for moveable structure type).

This version contains solutions for several problems or requests reported from our users:

• Corrected size of exported graphical symbols in landscape mode.
• Releases in plates and multistage models - change of release type through stages.
• Steel design for unsymmetric I profiles.
• Marks for reactions of linear supports - with small letters (to make them different from point support marks)
• Creation of envelope loadcases from combinations of moving and static loads.
• Proper order for node numbering in single linear element diagram display dialog and export.
