EXAMPLE 4. METAL STUDY CONSTRUCTION WITH 3D DWG

EXAMPLE: 'DESIGN OF METAL CONSTRUCTION' 44 The first two are the approximate methods of EC8-1. 1. In the first is necessary: select, per direction, the type of building on the right (in the case of X and/or Z where the structure consists a single frame, the following shall be activated the corresponding checkbox in the "Openings" box ) 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 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.
