The structure is designed with pre-stressing tendons that are assembled into segments prior to being installed, which increases their resistance to deformation and makes them resilient even under dynamic loading conditions.In these structures, plastic hinges play a critical role in the performance of the structure under seismic loads. Plastic hinges are regions where the material undergoes significant inelastic deformation, and they are responsible for the energy dissipation and stability of the structure during earthquakes. Therefore, understanding the plastic hinge mechanism is essential to ensure the safety and reliability of these structures.Objectives:The primary objective of this research is to investigate the plastic hinge mechanism in pre-stressed concrete structures with pre-tensioned assembly framework. This will be achieved by:1. Conducting a comprehensive literature review on the plastic hinge mechanism and pre-stressed concrete structures with pre-tensioned assembly frameworks.2. Developing a detailed model of the pre-stressed concrete structure and incorporating the plastic hinge mechanism into the model.3. Performing a series of nonlinear, dynamic analyses of the pre-stressed concrete structure under different loading 精品文档---下载后可任意编辑conditions to quantify the performance of the plastic hinge mechanism.Methodology:The research will be carried out in two main phases. The first phase will involve a literature review of plastic hinge mechanism, and pre-stressed concrete structures with pre-tensioned assembly frameworks. In the second phase, a detailed model of the pre-stressed concrete structure will be developed using finite element analysis. The model will be verified through experimental data available in the literature. Then, nonlinear dynamic analyses will be performed using OpenSees software.Expected outcomes:This study is expected to provide insights into the performance of pre-stressed concrete structures with pre-tensioned assembly frameworks during seismic loading. By investigating the plastic hinge mechanism, this study will provide valuable information on the energy dissipation and stability of these structures, which will ultimately enhance their safety and reliability.
