This service pack should be installed to ensure optimum function of the program. Several improvements and issues have been resolved including: Issues with Associated Bulletins. Flat Slab Punching Checks - Head Codes BS and Eurocode (All Countries/ Regions) - this issue applies only to punching checks inside slab column patches with reinforcement set to “None” and reinforcement only in the slab panel (which is unusual for typical flat slabs, but not impossible). In these circumstances the tension reinforcement ratio ⍴ used in the punching shear checks was double the correct value in both directions. Where this occurred it would produce an unconservative result for the slab shear capacity without reinforcement. See (13072).Enhancements & Fixes.
File Opening - an exception could occur when unexpected or invalid data was encountered during file opening (12991). Editing Geometry. Slab items - where a slab item overlapped another, it was difficult to select a selected slab item’s node in the overlapped area via the tool tip Select Entity list in order to move its position. This issue only affected the first release of 2016i and SP1 (13123). Members - where a selected member’s end node was overlapped by the rendered geometry of another member, it was difficult to select the node via the tool tip Select Entity list in order to move its position.
Roof Panels - in some circumstances a program error could occur on validation where a roof panel was incorrectly created such that one or more of its edges did not quite align with the members along that edge (12934, 52022). Analysis Elements - a validation error is now issued where analysis elements exist that are coincident with the elements of a concrete beam, which would cause analysis errors (12848). In some circumstances, where a number of columns were created with stacks inside a concrete wall producing an element collision, a program error could occur on validation (52115). General. Isolated Foundations - Head Codes BS and Eurocode (All Countries/ Regions) - for both Pile Caps and Pad Bases for some shear checks the shear resistance at the design section was not limited to the maximum allowable shear resistance (Cl 3.4.5.8 of BS-8110 and Section 6.2.2(6) of EN 1992-1-1:2004).
For Pile Caps the issue applied only to the shear capacity check and pile one-way shear checks, while for Pad Bases it applied only to the shear check at d from the column face. A product bulletin has not been issued because it seems highly unlikely this correction would be significant for any realistic pile cap or pad base arrangement (51981, 52015). Pile Cap Design:. BS & EC Head Codes - One-Way Shear - for square piles, the expression for enhanced shear resistance at the critical section incorrectly included a term (lp/2) producing an incorrect and too low resistance.

This could produce a fail status when the pile cap was adequate for one-way shear and lead to auto-design for depth producing a depth much larger than that required (12952). All Head Codes - One-Way Shear - enhancements made to the pile location checks ensure the correct one-way shear check is performed for corner piles (52030). All Head Codes - Punching checks - enhancements made to the pile location checks ensure the appropriate punching shear perimeters are checked. Previously, for some arrangements of piles and column positions, the column and pile punching checks could consider perimeters that were not required (52028, 52038).
Composite Beams - All Head Codes - when assessing moments on composite beams, the program now always uses the Ignorable forces limit value for major axis moment (Design Options Design Forces Ignore Forces Below).
Cast-in-place slab designs are becoming more challenging as architects push for thinner slabs and larger column spacings. Engineers are asked to push the boundaries of conventional CIP flat slabs and deflections become critical to designs. Even with existing technology this process can be extremely tedious with a large portion comprising of manual checks and iterations.
Flat slab design can be stressful budget breakers. Tekla Structural Designer’s new rigorous slab deflection capabilities efficiently addresses these challenges.
