Dynamic-SDOF-PHP-Class

PHP class for the dynamic analysis on single degree of freedom structure due to earthquake ground shaking.

  1. SDOF Class solve for the dynamic motion equation in which including inertia force, dumping force, elastic force of sdof structure to resist the forces due to ground shaking.
  2. Differential motion equation is discrete by using finite difference method. By this method, central difference method to solve response of SDOF structure.
  3. Ground acceleration data due to Kobe earthquake is used in test example.
  4. Analysis is carried on step by step time interval according to seismic record stored in kobens.txt.
  5. 2 analysis are implemented in class, RHA response history analysis and other is to generate response spectrum curve.
  6. Response spectrum curve help engineers to design earthquake resisting buildings.
  7. If one has accelerogram recorded by strong motion accelerometer, response spectrum graph can be easily driven by using SDOF Class.
