(2), cooperativity in space is unreasonable between each cantilevered structure layer, between the cantilevered structure layer contact of non-structure member or contact member a little less than, cause the basic independent stressed of each floor, lack more effective mass action.
(3), structural mechanics response is unreasonable because the mechanical characteristic of cantilevered structure, structure is encorbelmented, and effect is remarkable slightly for the end whip, obviously amplifies at static(al), dynamic responses such as the displacement of load action bottom, acceleration, influences safety, the function of use of structure.
(4), should not satisfy building height, large space instructions for use, because for satisfying the structural safety requirement, the cantilevered structure scantling is bigger, and along with the length difference of encorbelmenting, scantling size disunity, influence building usage space requirement for height, if in overhang layer inside vertical contact rod member is set, then influenced the large space instructions for use of building.
(5), the big cantilevered structure of multilayer is because its vertical rigidity is irregular, the unnecessary constraint degree of structure is few, be to guarantee structural safety, the structural timber consumption is higher, economy is relatively poor.
