22.2.0_ETA_frequency_domain_analysis
The following two types of frequency domain analysis have been added into ETABS:
- • Steady State analysis may be used in lieu of the more computationally intensive Time-History, often for cases where the initial ramp up or cool down periods are not considered important.
- • Power Spectral Density analysis is a method to perform a probabilistic evaluation of random vibrations across a frequency range.

Structural Model
21.2.0_ETA__frame_hinge_assign_presets
The frame hinge assignment feature has been enhanced with four new preset hinge assignment distribution types:
- 1. Beam Column, which adds a moment or PMM hinge at the ends of the frame object.
- 2. Distributed Plasticity, which adds hinges along the length of the frame object based on a specified integration rule.
- 3. Equal Spacing, which adds hinges at a fixed spacing along the length of the frame object.
- 4. Continuous Support, which adds one hinge at the center of every frame element associated with the selected frame object.
Analysis
21.2.0_ETA_multi-thread_solver
An enhancement has been made to allow the “Number of (Internal) Threads for Analysis" setting to also control number of threads that can be used by the Multi-threaded Solver. This creates less competition for resources and can speed up analysis.
21.2.0_ETA_modal_damping
An enhancement has been made to speed up direct-integration time-history load cases with additional modal damping specified for a large number of modes. For building structures, the higher-frequency modes typically respond statically to seismic and wind loading, and stiffness proportional damping is more efficient for the damping at high frequencies.
Output and Display
