Enhanced in the November ‌2024 Engineering Library update to incorporate frequently requested features including:

• design of unreinforced (plain concrete) footings

• new lateral and moment load types (live roof, snow & rain)

• new cross-section sketches in the interface and output

• perform a shrinkage & temperature reinforcement check when reinforcement not required for strength design (zero moment locations)

• improved loading details interface dialog

Enhancements to increase the scope and accuracy of design results.

• Added T-section design. This method increases the accuracy of results when a partially grouted reinforced wall is specified, resulting in less conservative results.

• Added SI unit version to the calculation.

• Added minimum/maximum reinforcement bar and spacing checks.

• Added minimum cover check including the option to specify a face that is exposed to weather or earth.

• Added the ability for the user to select standard block sizes to automatically populate block dimensional information.

• Added preview output to user interface so the detailed calculations can be investigated without finishing the calculation.

• Improved API to allow better API control of reinforcement selection.

• Improved calculation of cracked moment of inertia, Icr, facilitating more accurate p-delta design for partially grouted sections

• Calculate adjusted orthotropic properties for TSD interop based on specified bending axis.

• Enhanced the calculation to include an optional deflection check based on a user input of a first order deflection.

Enhancements to add the option of designing the stem as a masonry wall and to add preview results to the reinforcement dialog.

• Rearranged the reinforcement dialog so the full preview results can be viewed when selecting vertical and horizontal reinforcement.

• Added option to select masonry as a stem material.

• The masonry stem can be a concrete or clay masonry wall comprising of single-wythe construction featuring solid or hollow masonry.

• Hollow masonry can be grouted and may include vertical and horizontal reinforcement.

• The calculation includes designs following both the allowable stress design (ASD) and strength design (STR) methods.

• In accordance with TMS 402/602-22, TMS 402/602-16 and TMS MSJC-13.

A verification example compares the results of a specific Tedds calculation to published examples from trusted industry sources (AISC, ACI, NDS, etc.). The verification examples give you confidence that the calculations are accurate and reliable. Detailed documentation is provided in the Tedds Product Guide for each verification example.
