For all structural engineers and reinforced concrete designers: This engineering application for the iPhone or the iPod Touch calculates the dimensions and area steel reinforcement for rectangular and Tee beams (T-Beams) of reinforced concrete members. That includes single and double reinforced beams. The program calculates the strength of singly reinforced and doubly reinforced T and Rectangular concrete beams. It calculates positive moment, negative moment and shear. Based on given positive and negative moments the program calculates the balanced depth and balanced area of steel reinforcement. It also calculates the weight of concrete and steel and the total weight of the section. The program is based on ACI 318. Other codes will be added in future revisions. The balanced section and reinforcement and the strength is calculated in two methods: Working Stress Design (WSD) and Ultimate Strength Design (USD) which is also called Limit State Design (LSD) or Strength Design Method (SDM). The input is beam width, beam depth, areas of tension reinforcement and compression reinforcement, steel yield strength, concrete ultimate strength, size and spacing of sterrups, and for the T-Beam, width and depth of flange slab. to find the balanced section dimensions, you need to input the positive and negative moments and to find the strength you need to input the depth and areas of steel. The modular ratio (N) for working stress design can be input or calculated. The input can be in mm or inch units, the output is in mm or inch units. The weight can be displayed in kg/m or Lb/ft and the moments and shears are in kN, Lb, kN.m and Lb.ft. The input data can also be converted between the two unit systems.

It assists structural engineers and designers in determining beam strength and weight. ### What design methods does iConcrete support? iConcrete supports two primary design methods: Working Stress Design (WSD) and Ultimate Strength Design (USD), also known as Limit State Design (LSD) or Strength Design Method (SDM). This allows for flexible analysis based on different engineering standards. ### Can iConcrete handle different types of reinforced beams? Yes, iConcrete can calculate the dimensions and reinforcement for both single and double reinforced beams. It also specifically supports the design of rectangular beams and T-beams, including flange slab dimensions. ### Does iConcrete support unit conversions? Yes, iConcrete allows input and output in both millimeters (mm) and inches (inch). It can also display weight in kg/m or Lb/ft and moments/shears in kN, Lb, kN.m, and Lb.ft, with data conversion between unit systems. ### What information is required to use iConcrete? Required inputs include beam width, beam depth, areas of tension and compression reinforcement, steel yield strength, concrete ultimate strength, and sterrup details. For T-beams, flange width and depth are also needed. Moments and depths are required for balanced section and strength calculations. ### What is the rating of iConcrete? iConcrete has a rating of 3.0 stars based on 2 user ratings. This indicates a mixed reception from its user base. ### How often is iConcrete updated? The latest version of iConcrete is 1.05, which was last updated on October 10, 2021. While the app has been available since 2009, updates may not be frequent. ### Does iConcrete have ads? No, iConcrete does not contain advertisements. As a paid application, it offers an ad-free user experience. ## Version history (last 5 releases) ### 1.05 — 2021-10-10 Rebuilt to run on latest iOS. ### 1.04 — 2017-02-14 Bug fix: the input for area of steel is made accessible again. Sorry for inconvenience. ### 1.03 — 2017-01-17 iOS 10 compatibility. ### 1.02 — 2009-07-24 The calculation of balanced section for Strength Design Method is now performed when top reinforcement is less than bottom reinforcement. Initial Screen has been added. Larger buttons with added click sounds for confirmation of button press. Tested on iPhone OS 3.0. ### 1.01 — 2009-06-05 No release notes. ## Apps similar to iConcrete | App | Rating | Price | Category | | --- | --- | --- | --- | | [Visual Hear — Helper for Deaf](https://appshunter.io/ios/app/visual-hear-helper-for-deaf/id899882405) | — | Free | Productivity | | [PDF Scan - MAX Scanner](https://appshunter.io/ios/app/pdf-scan-max-scanner/id1438590887) | 4.5 (44) | Free | Productivity | | [Gantt chart AI planner Ingantt](https://appshunter.io/ios/app/gantt-chart-ai-planner-ingantt/id6466750274) | — | $14.99 | Productivity | | [Open Channel Flow Lite](https://appshunter.io/ios/app/open-channel-flow-lite/id1579229822) | — | Free | Productivity | | [Rectangular Beam](https://appshunter.io/ios/app/rectangular-beam/id1436344246) | 1.0 (2) | $4.99 | Productivity | | [Open Flow Pro](https://appshunter.io/ios/app/open-flow-pro/id376583527) | 1.0 (1) | $0.99 | Productivity | ## More apps by ahmj - [iSection](https://appshunter.io/ios/app/isection/id304905558) - [iSectionLite](https://appshunter.io/ios/app/isectionlite/id320141628) - [Quick Arabic Keyboard](https://appshunter.io/ios/app/quick-arabic-keyboard/id951544975) All apps by ahmj: https://appshunter.io/developer/304905561 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
