8A. ANALYSIS Part 1: NEW BUILDINGS

CHAPTER 8A 'ANALYSIS' 45 Enter the min Length (cm) and press the command "min Column Length" to automatically determine the walls per direction, so that the calculation of T1 is done according to par.4.3.3.2.2. 2. The second approximate method , is sufficient to be selected and does not require any additional action. 3. The third possibility is to calculate the eigenpipes by Idiomorphic Analysis. The program takes as the building's eigenvector per direction the eigenvector corresponding to the dominant eigenmode (the eigenmode with the highest percentage of activated mass). The user can increase or decrease the number of Idiosyncrasies, in case of dynamic analysis, and Static, in case the user chooses to calculate the eigenvalues from Idiomorphic Analysis, and the accuracy rate. It is also possible to choose the mode of overlap of the eigenmodal responses either according to the Full Quadratic Parallelism CQC and CQC(10%) rule (3.6 EAK), or the Simple Quadratic Parallelism SRSS rule. Also, the results of the seismic action now include the results of the eigenmode analysis for the static scenarios.
