IDEA StatiCa Detail
IDEA StatiCa introduces a novel way to design and check concrete details and walls. With it, engineers can break
the limits of standard design tools to save time and optimize the material usage. Clear pass/fail checks according
to the code are available in minutes, as well as complete output reports.
IDEA StatiCa Detail deals efficiently with all parts of structure also known as discontinuity regions such as walls,
dapped ends, openings, hangings, brackets, and areas above supports. It provides precise checks of concrete
and reinforcement strength, stresses and strains. These results are clearly visualized for better understanding
of details of structures.

- improved possibilities for no concrete resistance in tension:

Always - The assumption that the concrete resists no tension will be applied in all SLS checks for all combinations of all sections and their extremes.

Section - In the case that upper or lower design value of internal forces of one of SLS combinations will cause concrete stress higher than concrete tensile strength, the assumption that the concrete resists no tension will be applied in all SLS checks for all combinations of all extremes of current section. The assumptions for SLS checks in other extremes of current section will not be influenced.

Extreme - In the case that upper or lower design value of internal forces of one of SLS combinations will cause concrete stress higher than concrete tensile strength, the assumption that the concrete resists no tension will be applied in all SLS checks for current extreme only. The assumptions for SLS checks in combinations of other sections will not be influenced.


- support for AxisVM12 release 2

- fix in crack width calculation

- Erroneous influence of secondary prestressing effects appeared in XY plane of 2D XZ model of straight beam.

It happened as a result of boundary conditions incorrectly generated for 3D FEM solver.

The bug appeared in case that the point of application of resultant prestressing force fell outside of vertical XZ plane going through cross-section centroid

(e.g. in case of non-symmetric prestressing reinforcement). The bug caused the deviation of 15% from correct internal forces on tested example.

- Incorrect value of the load was fixed in construction stage analysis. The load was caused by reverse reaction generated in removed nodal support,

which had existed in one node in more than one consecutive construction stages

- Incorrect value of the eccentricity was fixed in Time-Dependent Analysis of composite beams.

The eccentricity of reference line and the centroid of transformed cross-section was doubled,

with the impact on equivalent load caused by prestressing. The bug caused the deviation of 10% from correct results of cross-sectional checks on tested example.
