2. Benchmark solution

2.1. Calculation method

The reference result was obtained by calculating the floor envelope spectrum (level 1) of the building using conventional commands, commands grouped under command MACR_SPECTRE.

2.2. Benchmark results

The envelope floor spectrum obtained for damping equal to \(\mathrm{0,05}\) at the various frequencies is presented below.
