EXAMPLE 6. BUILDING VALUATION & REDESIGN STUDY

EXAMPLE 6: "STUDY FOR THE VALUATION AND REDESIGN OF A BUILDING ACCORDING TO THE CANC. 84 3(a).5.2 Bilinear Capability Curve This is the corresponding bilinear curve calculated either in the simplified way provided for by the CEEAP, or by calculating equal areas. The key concerns the definition of the parameters for the way of bilinearisation of the capacity curve of the structure. CAN.EPE 5.7.3.4 Idealised force-mobility curve The non-linear force-displacement relationship linking the base shear and the displacement of the control node (§5.7.3.1a) shall be replaced by an idealised curve to calculate the equivalent lateral stiffness Ke and the corresponding yield strength Vy of the building. The key button to define the parameters for the bilinearization of the construction capacity curve. This bilinear curve is necessary so that the slopes of its two branches can be used to calculate the eigenperiod and the corresponding spectral acceleration. Selecting it displays the following dialog box
