EXAMPLE 6. BUILDING VALUATION & REDESIGN STUDY

EXAMPLE 6: "STUDY FOR THE VALUATION AND REDESIGN OF A BUILDING ACCORDING TO THE CANC. 63 The horizontal static loads will be applied at the level of each diaphragm (floor slab), according to the distribution of the inertial loads of the earthquake. All analyses shall require the application of at least two different load distributions per height, in order to take into account (as far as possible) the variation of load distribution due to the meteorological behaviour of certain areas of the structure, but also due to the influence of the upper eigenmodes. - Also, if you want to take into account, in addition to the seismic forces, moments resulting from the accidental eccentricities, activate the fields "Accidental eccentricities Eh and Ez". - "Select Base Cutting Force from Design Spectrum" when checked, uses as base cutting force the one calculated by the dynamic analysis. Selecting all combinations with the random eccentricities produces a total of 64 combinations which means 64 inelastic analyses resulting in an increase in vector resolution time. • Here are the parameters listed in the following section In the option " Active Wall Fillings " we select whether we want to take into account in the analysis the wall fillings that we have included in our construction . In the option " 2nd Order (i) Influence Check we choose to perform the relevant check. " Control node " you specify the number of the control node on the basis of which the targeted movement will be calculated. CAN.EPE 5.7.3.2 Definition of the control node The control node of the targeted movement will generally be taken at the centre of mass of the roof of the building. For buildings with attics or small dwellings in the attic, the control node shall be taken at the roof of the full underlying floor. The movement of the control node shall be calculated from the simulation analysis for horizontal static loads.
