Analysis of RCC Structure vs VerCivil

RC456Mason is an app that helps to run on-site analysis of basic RCC structure and its elements using limit state of collapse method as per Indian Standard IS 456-2000. In addition it checks for certain key compliance requirement as per IS code for structure integrity based on the actual data provided for analysis before casting. This is briefly described below. RCC Structure Elements: 1. Slab a.Simply Supported (Wall-rest) b.Cantilever c.Continuous 2. Beam 3. Flanged Beam a. T beam b. L-Beam c. Isolated 4. Column (Square/Rectangular) 5. Round Column 6. Footing 7. Staircase-A (on Slab) 8. Staircase-B (on Beam) Home Screen: A typical home screen as shown in screen shot has a element picker with related default dimensions. Users can select any element with grade of concrete and steel used and dimensions as per the given application for analysis. App uses only SI system of units for all data input and output. Analysis: The analysis screen will also have certain default data pertaining to the load and reinforcement bars. Users can edit these data based on the actual application and measurement. This is to make sure all the data entered are correct. Once entered report is presented in a scroll-able text view as shown in the screen shots. Report: Report includes results from stress and moment computation, concrete volume and weight estimation of both cement and steel that helps in material requirement planning. All the relevant clauses applicable as per IS 456-2000 that are also indicated in the report that can be reviewed in a separate screen. A RCC structure may have many different elements such as footing, column, beam, slab etc. Therefore each structure can be saved with unique title where one can add as many elements to this structure with reference name or code number for identification. A file summary is also provided that gives total structure summary along with individual element material summary as shown in the screen shots. Users can also create many different files for the same structure for design and cost optimization. IS456: Complete document of IS456 is made freely available at Bureau of Indian standards for the benefit of public at large. A few important tables and figures that are relevant to the given element analysis is presented in this app for convenience. The review screen has a scroll-able text view as well as image view and navigation buttons are provided to switch between images. Check List: A short checklist for given structure element can be reviewed from the home screen that provides type of data information one should collect that is used in the analysis. This would further ensure correctness of all input data. Notes: Help notes provide a short introduction to analysis procedure followed including reference to different clauses as per IS 456:2000. A help link is provided to download this document from Bureau of Indian Standard's web site. Use the following resource link for more details on different case illustrations on each of the above RCC elements. In each case a detailed theoretical analysis is performed using the model used in this app for better clarity. The pdf file contains the steps involved in arriving at the results shown in the respective screen shots and users can download this file for reference and program validation. www.flowjoule.com/rc456mason/rccMason.html This is updated using Xcode 14 for iOS 16 and targeted devices with iOS 12 and higher.
