This document discusses different types of analysis for systems with two degrees of freedom under various types of excitation, including elastic analysis, inelastic analysis using the Newmark method and hysteretic bilinear models, and applications like studying response to forced and seismic excitation and comparing elastic and inelastic response. It also mentions using the OpenSees software for analysis based on load functions, recorded seismic data, and important modeling features like direct damping elements.

- 1. Analysis of history in time of systems with two degrees of freedom
- 2. Types of analysis : Elastic analysis of history at the time Two types inelastic analysis of history at the time
- 3. Types of excitation Load linear function Load trilinear function Load harmonic function Record seismic acceleration
- 4. Important features Use OpenSees software Analysis based on the Newmark method The damping is established directly with damping elements Analysis inelastic uses two hysteretic bilinear model (Bilinear 1 y Bilinear 2)
- 5. Applications : Study of the response to forced excitation Study of the response to seismic excitation Comparison between elastic and inelastic response
