QUICK REFERENCE! This ready reference app from the Concrete Reinforcing Steel Institute is a handy desk and field resource and includes information on ASTM standard reinforcing bars (rebar), standard hook details, standard stirrup/tie hook details, and ASTM reinforcing bar marking requirements. The app provides standard rebar specifications including sizes, diameters, areas and weights along with 90-, 135- and 180-degree hook details. Minimum yield and minimum tensile requirements per ASTM are also included. Industry standard bar markings for inch-pound rebar is illustrated for grades 40, 50, 60, 75, 80, 100 (A615), 100 (A1035), and 120. Links to the CRSI’s online resources are included.
Beam HPC
This app calculates structural diagrams for beams, including moment, shear, and deflection. It supports various loads, supports, and material properties, allowing for interactive adjustments and comparisons. Designed for educational purposes, it helps users visualize and understand beam behavior.
- Moment, shear, and deflection diagrams
- Multiple load types (forces, moments, distributed)
- Adjustable support conditions (pinned, fixed, roller)
- Segmented beams with varying properties
- Interactive drag-and-drop interface
- Educational focus on beam behavior

Beam HPC app calculates the moment, shear, deflection and rotation diagrams for a beam with various types of loading. Loading types include forces, moments and distributed loads. The load location and magnitude can be changed at any time. There are three types of supports (i.e. boundary conditions) including pinned, fixed and vertical roller. Each beam can be split into sub-beam segments. Each beam segment can have a different moment of inertia (I) and stiffness (E). The user can click and drag all items to quickly change and compare results. This program is designed for educational uses only. It should not be used for commercial purposes. There is no warranty or guarantee the results are accurate, and the user accepts all responsibility for values calculated.
