EXAMPLE 6. BUILDING VALUATION & REDESIGN STUDY

EXAMPLE 6: "STUDY FOR THE VALUATION AND REDESIGN OF A BUILDING ACCORDING TO THE CANC. 44 deformable, the rule may be used that the relative floor arrow on either side of the building shall not exceed 150% of the through the relative arrow. (except ο last floor and annexes). As a criterion for this condition, the rule may be used that the average relative arrow of a floor (excluding appendages) shall not exceed 150% of the relative arrow of the underlying or the floor above. (iv) The building does not exhibit a strongly asymmetrical distribution of stiffness in plan view on any floor. No required check of this treaty on sufficient mixed systems. (i) the building in sectional height does not exhibit an asymmetrical distribution of mass;or of stiffness. (ii) The building has a system for absorbing seismic actions in approximately two vertical directions addresses between them. The main objectives of this paragraph are, on the one hand, to prevent the exclusion of the method (which has the well-known advantages of simplicity and transparency), due to the fact that all the conditions application of the §5.5.2a , particularly in older buildings, and the possibility of using the same method of analysis both in assessment and in the redesign (in which case, because of the interventions, it is more likely the conditions for application will be met). β. Notwithstanding the validity of conditions i, iii, iv and v of the previous paragraph, but that there is no substantial damage, the static elastic method may be used for the purpose of valuation (only). In this case the simulation safety factors γSd provided for in § 4.5.1 shall be increased by 0,15. CAN.EPE 5.6.1 Conditions of application (Elastic Dynamic Analysis) For the elastic methods there is no question of conditions of application relating to the level of confidence in the data. α. The scope of the dynamic elastic method is defined by the condition that for all principal elements λ ≤ 2.5. or for one or more of them λ > 2.5 and the building is morphologically normal.
