ABSTRACT
Study of damped structure performance mainly relies on types of dampers and configurations of their installations. The authors’ intention being the same as mentioned in Chapter 2, this chapter only addresses commonly used types of dampers, and introduces corresponding basic theories and their important applications to damped building structures. In addition, this chapter could be considered as a stepping stone for reader’s further studies. A brief summary of this chapter is presented as follows. In Section 3.1, basic concepts of damped structures with single or multiple degree-of-freedoms are introduced with consideration of nonlinear behavior of both building structures and dampers. Different analytical procedures with ASCE 7-05 [1] requirements are explained in detail in Section 3.2. Section 3.3 provides design examples according to ASCE 7-05 requirements. Testing requirements and properties verifications of dampers are summarized in Section 3.4.
