Design a dual (frame+wall) system by providing reinforced concrete walls with an area equal to about 0.1% of the total floor area in each direction (X, Y). The walls may have a

the thickness of 0.35 m and should be placed as symmetrically as feasible with respect to the mass centre, while the architectural /functional requirements are that no walls are permitted

along the front façade of the building, and the length of any wall should be such that free space of at least 1.5 m is left at any span.
