Major overhaul of the structural analysis module, Incorporated a post-debonding FRP resistance curve model and compression membrane arching action model. Minor bug fixes to SDOF and PI diagram modules. RCBlast now automatically checks the web for a new version on start-up. Minor change in the way unloading stiffness is calculated for hysteretic modelling. Added initial conditions to the SDOF module. Corrected a bug that prevented the user-defined pressure-time history from being correctly written to the save file. Corrected a bug which prevented pressure-time histories from being loaded from *.SDOF files, and improved the performance of the PI diagram solver. Added "Export to CSV" (comma-delimited text file) options for both SDOF and PI results. Numerous updates to the structural analysis module: the user can now fine-tune the moment-curvature solver settings validation of input data has been streamlined, and corrected several GUI-related bugs. Other GUI related updates: added splitter on main SDOF screen added contextual help to most windows, and "Export to CSV" feature re-written. Reduced the number of moment-curvature points stored within the program greatly improving performance and reducing storage requirements. Corrected a bug in the FRP stress-strain model and improved the manner in which FRP is displayed on the cross-section. Added sample input files to help new users learn the features of RCBlast. The Help File and sample input files have also been updated.

Numerous bug fixes, performance tweaks, and code optimization were also implemented. New feature called "Accumulated Damage," useful for modelling structures with reduced elastic stiffness due to previous cycles of inelastic response, has been added to SDOF module. Numerous bug fixes and improvements: (i) Corrected an error in the way time step is computed during development of PI diagrams affecting the pressure asymptote (ii) corrected a bug where the SDOF analysis in "Maximum Displacement Mode" could run for too long (iii) corrected a GUI bug which occurred when the user clicked "Cancel" in the Structural Analysis Module (iv) corrected an issue with the date-time picker which could cause the program to crash upon opening *.SDOF files (v) minor GUI updates.

My entry in the normal strength materials/SDOF modelling category won first place in the contest, while my entry in the high strength materials/SDOF modelling category placed second! In honour of this, I'm posting an updated version of RCBlast, with the following improvements: (i) added a perfect-plastic hysteretic model suitable for dynamic analysis of steel structures (ii) incorporated a PDF report generator to facilitate transmittal and storage of analyses (iii) corrected several bugs and improved SDOF solver performance (slightly) (iv) updated the donation screen (v) minor GUI updates, and (vi) updated the Help File. RCBlast was used exclusively for the analysis. I'm in Phoenix, Arizona at the American Concrete Institute's Fall Convention presenting the results of an SDOF analysis I performed as part of a blind simulation contest sponsored by ACI. This feature is particularly useful for an upcoming paper I am writing since it facilitates the study of the accumulated damage phenomenon by readily outputting initial conditions for subsequent dynamic analyses. This can be accessed through the context menu by right clicking on the displacement plot. The tooltip now displays detailed information (time, SDOF displacement, velocity, & acceleration) when the user hovers over a particular point on the plot. I also updated the SDOF Displacement-Time History Plot tooltip message.

Minor RCBlast software updates, including improved save/load GUI functionality and a prompt to ensure the user has saved their analysis prior to closing the software.
