The purpose of this work is indicating System Dynamics Approach to be an appropriate tool for analysis of policies suggested for local sectors. Local sectors are very important for stability of the country&rsquo / s economy as well as welfare of the local community. Therefore, feasible and effective policies should be created and implemented in order to contribute to the local sectoral development. But before any policy implementation, policy analysis is required on to evaluate whether effectiveness and feasibility would be ensured in alternative policies. In this study, firstly the issues of Local Sectoral Dynamics and Policies are examined and specifically, the situation in Alanya Tourism Sector is studied. Afterwards, in accordance with policy analysis steps, problems of Alanya Tourism Sector are detailed and alternative policies that would aid in solution of the problem are idenfined. For evaluation of alternative policies, Dynamics of Alanya Tourism Sector are modeled by System Dynamics approach and the &lsquo / Formal Model&rsquo / is implemented in Stella 9.0.1. The model is simulated for all policy alternatives and the policy outcomes of each alternative are forecasted. Finally the performance of each policy are evaluated using the previously established criteria and combined policies having more superior outcomes than the present ones are created.

In recent years, an increase to design slender and aesthetically-pleasing structures have resulted in some structures having a low natural frequency. This is because the design calculation did not meet the requirement of serviceability performance. Structures can experience excessive vibrations when they are subjected to different types of dynamic loading. A device can be installed to prevent these vibrations.In this thesis, we study the response of buildings and lateral vibrations of footbridges equipped with Tuned Liquid Damper. The aim is to mitigate the first mode of vibration. Tuned Liquid Damper consists of a container in rectangular, cylindrical or arbitrary shape partially filled with shallow liquid, most often water is used as a regulating device system. The design properties of Tuned Liquid Damper is introduced and it is based on the analogyof the most popular damper, Tuned Mass Damper.An experimental study of a building frame model with four floors is conducted to validate the numerical results obtained from the simulation of the model in ANSYS. The linear and non-linear analysis are performed through a system coupling between Ansys mechanical and Fluent solver. The simulation results obtained are in good agreement with the experimental results.A parametric study is conducted with a simply supported steel footbridge. It is a 45 m long span with 3 m width and the flexural rigidity is modified to get the lateral vibration mode. The first lateral natural frequency obtained is 0.713 Hz. The load case for the study considered is according to Sétra guide. The variable parameters studied is the Tuned Liquid Damper water mass ratios: 0.7%, 1.0%, 2.0%, 3.0% and 4.0%. The results show a satisfactory performance of the footbridge model equipped with Tuned Liquid Damper. The accelerations are below 0.1 m/s2 which satisfied the requirement of 0.15 m/s2.
