## 3 Results
A comprehensive overview of results (including several cases) for THMA (error 1) at average of stories, first story and roof) is offered in Figure A3 (\(u_{1}\) and \(\Delta_{1}\)), Figure A4 (\(\
abla_{1}\) and \(a_{1}\)) and Figure A5 (\(V_{\text{S1}}\), \(V_{\text{D1}}\)) included in Appendix D; in these figures for every case, variable and story: (i) a modified whisker-and-box diagram (referred hereinafter as bar plot) is produced, where the \(x\)-axis represents the value of the error and the extension of the base line is indicative of the full range of error results; (ii) a thick line indicates the range comprised between 10% and 90% percentiles, with the median indicated by a circular hollow marker; (iii) for each case, numerical values are indicated for the maximum (green, labeled max) and minimum (red, labeled min) errors, as well as for the 10%, 50% and 90% percentiles; iv) an indicative EAR is marked by vertical dash-dot lines at errors \(-\)0.15 (red) and +0.25 (blue), to help in visual comparison of the plot horizontal scale. As an example, focusing in Figure A3a, and case B3-1, the min, 10%, 50%, 90% and max errors, respectively, are: for the average of stories \(u_{1,\text{error,average}}\): \([-\)0.23, \(-\)0.07, \(-\)0.01, +0.05, +0.41]; for the first story \(u_{1,\text{error,first}}\): \([-\)0.44, \(-\)0.17, \(-\)0.04, +0.17, +2.08]; for the roof \(u_{1,\text{error,roof}}\): \([-\)0.31, \(-\)0.08, \(-\)0.00, +0.01, +0.04]. For brevity, similar plots produced for RSA-SRSS (error 2) and RSA-CQC (error 3) for all relevant variables, are included as Supplementary Materials: Figure S3 (\(u\)); Figure S4 (\(v\)); Figure S5 (\(\Delta\)); Figure S6 (\(\
abla\)); Figure S7 (\(a\)); Figure S8 (\(V_{\text{S}}\)); and Figure S9 (\(V_{\text{D}}\)). Additional scatter plots relating the first story THMA error with the roof THMA error for case B3-1 are given in Figure 6. Finally, a numerical summary of results is given in Table 2 (frame-type systems, B0-1, B3-1, B5-1, C3-1, B3-0.5, B3-2) and Table 3 (shear-type systems, B0-\(\infty\), B3-\(\infty\), B5-\(\infty\), C0-\(\infty\), C5-\(\infty\), C5-\(\infty\)), where the mean \(\mu\) and standard deviation \(\sigma\) of five statistics (min, \(x^{10}\), \(x^{50}\), \(x^{90}\), max) across cases is calculated for every variable and story. For instance, in Table 2, the mean (\(\mu\)) and standard deviation (\(\sigma\)) for variable \(u_{1}\) corresponding to first story and \(x^{10}\) are \(\mu=-0.17\), \(\sigma=0.01\), obtained as statistics of 6 values of \(x^{10}\)\([-\)0.18, \(-\)0.1
