TRACK 1 Output
Setting the program to output the beam design with a TRACK 1 option will perform full design and detailing operations and will report a summary of the design. A TRACK 1 report will include the following sections:
- Design Summary
- This section provides a summary of the design including the design status (i.e., PASS/FAIL), member type, length, the critical ratio, the critical criteria, and relevant clauses.
- Cross section details
- This section provides shape type and dimensions of the cross section profile.
- Longitudinal Bar Layout
- The position and extent of the longitudinal bars will be reported along with an indication if additional anchorage is required at the start or the end of the bars. A value of "yes" in the Anchor column indicates that the bar or set of bars will need to be anchored beyond the given section distances. This can be done using hooks/bends or physical anchors as deemed fit. A value of "no" indicates that no additional extension to the bar is needed beyond the given dimension. The value given in "Distance from face"is the measurement from the face defined by the position, to the center line of the bar, measured perpendicular to the face.
- Transverse Bar Layout
- The transverse bar table reports the details of
various shear zones (see
D1.F.4.3
Shear and Torsion Design ) within the span for both the local
Y & Z axes.
Each zone is identified by the unique start and end location reported as the distances "From" and "To."
This provides shear densities as minimum required and as provided by the given bar details.
The value "Nums" is the number of transverse groups in the zone (this equates to the zone length/spacing +1), the center to center spacing between adjacent transverse groups along the local X axis, the size of the bar used in the transverse group, and the leg count for the bars in a transverse group. A transverse group is the collection of transverse bars at a given cross section.

TRACK 2 Output
TRACK 2 will produce the results of TRACK 1 along with the details of the bars and their distribution at each cross section. This option will also report any of the relevant detailed design messages. The longitudinal bar details at each cross section will have information on the setting out of each bar at the specific cross section. This should serve as a useful tool to inspect the design in detail. A TRACK 2 output would contain:
- Design Summary
- This section provides a summary of the design including the design status, i.e. PASS/FAIL, member type and length, the critical ratio, the critical criteria and relevant clauses.
- Cross Section Details
- This section provides the shape type and dimension(s) of the cross-section
- Design Inputs
-
This section reports the material data for the steel and concrete including the yield strength for steel (FY), compressive strength of concrete (FC) and modulus of elasticity for both (Es and Ec) This section additionally includes details of the cover to the longitudinal bars from the top, bottom and side faces.
- Critical Strength Results
- This section reports the demand determined from the design envelope as described in D1.F.4 Beam Design , along with the capacity for forces applied in positive and negative directions. The ratio is then the value of the demand divided by the appropriate capacity.
- Longitudinal Bar Details at Cross Sections
- For each of the design cross sections, the
longitudinal bars are reported for each face where they are required, top
bottom and skin. Area of steel is reported as the optimum required from the
design and that provided after additionally meeting the detailing requirements.
The total quantity of bars on the given face are reported as "No(s) bars," the size of longitudinal bars and quantity of layers that the bars are to be distributed on. For example, if the number of bars reported is 10 and in 2 layers, then there will be 5 bars in each layer.
- Longitudinal Bar Layout
- The position and extent of the longitudinal bars will be reported along with an indication if additional anchorage is required at the start or the end of the bars. A value of "yes" in the Anchor column indicates that the bar or set of bars will need to be anchored beyond the given section distances. This can be done using hooks/bends or physical anchors as deemed fit. A value of "no" indicates that no additional extension to the bar is needed beyond the given dimension. The value given in "Distance from face"is the measurement from the face defined by the position, to the center line of the bar, measured perpendicular to the face.
- Transverse Bar Layout
- The transverse bar table reports the details of
various shear zones (see
D1.F.4.3
Shear and Torsion Design ) within the span for both the local
Y & Z axes.
Each zone is identified by the unique start and end location reported as the distances "From" and "To."
This provides shear densities as minimum required and as provided by the given bar details.
The value "Nums" is the number of transverse groups in the zone (this equates to the zone length/spacing +1), the center to center spacing between adjacent transverse groups along the local X axis, the size of the bar used in the transverse group, and the leg count for the bars in a transverse group. A transverse group is the collection of transverse bars at a given cross section.
