The HIT-calculation software allowsthe engineer is able to establish anoptimal balcony slab connection,taking into account the system de-sign, dimensions and applicableloads.

Furhtermore several variations ofthe connection concerning fire pro-tection, kind of slab or the optimumcut-to-size layout can be pre-selected.

In the "status"-line several supp-lementary information are shown, e.g. about the cut-to-size configurati-on and subsequently a reduction ofthe allowable load per element.in this field chose the calculation

method :a) Finite ElementMethods (FEM),b) Procedure acc. to Stiglat/Wippel(S/W)Using the Finite Element Methodsalternatives are possible betweenrigid and elastic supporting.

Different procedures for the calcula-tion and selection of the HIT-elements can be chosen by a symbolbar in themain inputwindow:Cases 1 and 1.1 are based on your

own calculation of the cross sectio-nal forces;in the cases 2.1 to 2.6 the calcula-

tion (and by this way also the calcu-lation of the cross sectional forces) iscarried out based on the respectivestructural situation. In these cases aschematic drawing appears in ,where the necessary geometricaland load specific data are shown.The screen „input“ is automatical-ly adapted to the actual case ( ), theinput casings which are not used arenot shown.Many parameters can beput in, such as e.g. the panel dimen-sions, different load modes and thecalculated support depth. If theinputs are not in accordance withthe prescriptions of the DIN stan-dard, awarning appears.

After striking the key "new calculati-on“ the screen "Edit“ shows allcalculation results as well as desig-nation and number of the chosenHIT-elements.

The HIT system has been designed fora reinforcement lap in the tension zoneas shown on page 29 (chart 1: singlelayer lap joint; chart 2: two layer lapjoint).

If you use other arrangements ofreinforcement a separate calculation isrequired.

The laps for the load range 10/7 to12/10 are 54 cm and for the loadrange 12/12 to 14/12 are 63,5 cm.

If the actual design load is less thanthe allowable load, the lap length canbe reduced by the ratio requ.a /actuala .

Spacing of installation

According to the official approval certificate the spacing between the tension- andcompression bars must be at least 5 cm and it may not exceed 50% of thepermissible maximum spacing (0,5 × 30 cm).
