The structure is unstable at (a). Revise the structure. An error has occurred: (a) has horizontal loads, but the structure is automatically stabilized in the X and Y directions The code rules selected in Rule Set "Service" (Sustained Service / Max Service) do not appear compatible with the load factors in the load combinations using the rule set. This is likely an error. Load Combination "Service" (Sustained Service / Max Service) has unusual balance and / or hyperstatic load factors. This is likely an error. Rule Set "Strength Design" is being used by load combinations that appear to have load factors set for different purposes. This is likely an error. The mat / raft is likely unstable. There is less that 25% contact area. Punching Check #a is not located at a column Too many slab shapes intersecting the column shape at (x,y) An error has been found. The cross section trimming for strip ab-c has caused there to be no concrete remaining at one or more locations. An error has been found. [Design strip] ab-c has reinforcing bars with too much cover (the bottom bar is closer to the top than the top bar). A cross section in design strip ab-c has no shear core A cross section in design strip ab-c has a very small shear core ab-c contains user transverse reinforcement but has multiple shear cores. Shear/torsion calculations may be approximate ab-c contains user reinforcement that is not within the primary (largest) shear core. This transverse reinforcement will be ignored An error has been found. ab-c contains multiple user transverse rebar regions Parent topic: Warnings and Errors
