Design principles for load-bearing calcium silicate structures
In order to achieve an optimal performance with load-bearing calcium silicate structures it is recommended that both the architect and the builder take account of the following points of interest: •Make the building layout as symmetrical as possible. In rooms that are mutually separated by structural walls. •These structural walls should be projected vertically above each other in successive building levels so that continuous plates are formed. •The walls required for stability must not be overly weakened by placing large openings in unfavourable positions. Openings that do occur should be vertically above each other on successive floors as far as possible. •Deviations in the regularity of the wall pattern are permitted; additional provisions must be included where necessary. •The floors should be designed such that, as rigid plates, they are capable of transferring the wind load from the facades to the stabilising walls or "rigid cores". Monolith reinforced concrete floors and so-called “shell floors” with a poured concrete topping are most suitable for this purpose. When using hollow concrete plank floors it is often necessary to take measures to ensure the "plate effect". This can be achieved by applying a concrete topping or incorporating so-called tensioning rods. •There should be stabilizing walls or “rigid” cores present over the entire height of the building down to the foundations for the required building stability and to absorb the wind load in both main directions. Stability can be provided by transverse walls or façade piers of adequate dimensions. Stairwells and lift shafts are often suitable as stabilizing elements.
