WeldEquations vs CSiRebar

Useful for the preliminary sizing of welds, WeldEquations is an engineering calculator app that computes the section properties for typical welding patterns used in steel construction. After selecting a Weld Group, the user enters the dimensions for the depth and width. The section properties for the Weld Group, including the area, section moduli and polar moment of inertia, are instantly calculated. For practicality, both weld group dimensions are limited to a minimum of 0.25" and a maximum of 100".  The equations used by the app are available for reference and manual verification.

CSiRebar is an app that conveniently converts between combinations of bar sizes, steel area, and spacing requirements. Application/Usage: • Convert between combinations of bar sizes, steel area, and spacing requirements • Select the required combination of bar sizes and spacing for given conversions using ASTM, Metric or Imperial standards Target Users: • Structural and civil engineers who need to view and select from various reinforcement layouts for a given criteria during member design • Structural and civil engineers who need to quickly get the area of steel provided in a given section during member analysis Key Features: • Generate many reinforcement layouts • Provide ability for combined reinforcement layouts • User-defined rules for bar selection • Provide several bar options for user-defined range Key Input: • Area • Bar size • Number of bars • Bar spacing • Combined reinforcement layouts Key Output: • Area for given reinforcement layouts • Reinforcement layouts for given bar options and spacing requirements • Alternative reinforcement layouts for given layouts
