- Abstract
- This report summarizes the results obtained by Earthquake Engineering Research Center personnel during a cooperative investigation with the Center for Earthquake Engineering Research (CEER) of National Taiwan University, Taipei, of the dynamic behavior of Techi Dam. Part I describes a field study of Techi Dam, a doubly curved arch dam 590 ft high located in central Taiwan, using rotating mass vibration generators. The measured vibration mode shapes, frequencies, and damping ratios are reported. Part II describes the analysis of the vibration mode shapes and frequencies using the computer program ADAP. In addition to the ADAP finite element models of the dam and foundation, this analysis also made use of a subroutine RSVOIR, which modeled the incompressible reservoir interaction effects both by an extended Westergaard procedure and also with liquid finite elements. Part III presents the stresses calculated in Techi Dam when subjected to the Design Basis Earthquake which was formulated for this site by CEER.
