Chapter 1. Introduction

Abstract

This chapter gives a brief introduction to sliding base (SB) structures. The basic idea of SB structures is interpreted, and experimental studies on the properties of potential materials for using in the sliding interfaces and analytical studies on the responses of SB structures under harmonic and earthquake ground motions are reviewed.

Chapter 2. Responses of 2DOF Sliding Base Systems Under Harmonic Ground Motions

Abstract

Although actual structures would not be subjected to harmonic ground motions, theoretical solutions obtained under harmonic ground motions can often provide useful information for understanding the mechanism of the structures considered. For this reason, this chapter focuses on the responses of 2-degree-of-freedom (2DOF) sliding base (SB) systems subjected to harmonic ground motions. The main contents of the present chapter include the typical response histories of a 2DOF SB system subjected to harmonic ground motions, the influence of the critical parameters on the maximum structural responses, and the derivation and interpretation of the available theoretical solutions.

Chapter 3. Response Histories of Sliding Base Structures Under Earthquake Excitation

Abstract

In this chapter, the equations of motion for multistory sliding base (SB) structures under three-component excitations are established, and numerical methods for computing the response histories of SB structures are also developed. Typical response histories of SB structure under earthquake excitation are presented, aiming to provide the readers an overview of how a SB structure response when subjected to earthquake excitation. This chapter lays a foundation for the following chapters, which focus on specific aspects of SB structures, respectively.

Chapter 4. Peak Superstructure Responses of Single-Story Sliding Base Structures Under Earthquake Excitation

Abstract

Compared to multistory sliding base (SB) structures, single-story SB structure is simple and suitable for acquiring the critical parameters influencing the structural response. For this reason, this chapter focuses on the peak superstructure responses of single-story SB structures subjected to three-component earthquake excitation. The influence of the vertical earthquake component and various structural and ground motion characteristics on the peak superstructure response are investigated, and simplified design equations are developed. The developed equations also lay a foundation for the design of multistory SB structures, which will be discussed in the next chapter.

Chapter 5. Equivalent Lateral Forces for Design of Multistory Sliding Base Structures

Abstract

In Chap. 4, the peak superstructure responses of single-story sliding base (SB) structures subjected to three-component earthquake excitation were studied, and simplified equations for estimating the peak superstructure responses were also developed. For multistory SB structures, these equations may still be used to determine the total earthquake force acting on the superstructure; however, they are not sufficient to determine the earthquake forces acting on each story of a multistory structure. For this reason, this chapter focuses on the development of equivalent lateral forces for the design of multistory SB structures.

Chapter 6. Peak Sliding Displacements of Sliding Base Structures Under Earthquake Excitation

Abstract

To ensure the safety of sliding base (SB) structures, the peak sliding displacement (PSD) should not exceed the predetermined sliding displacement threshold. Therefore, the PSD is an important response quantity that should be evaluated in design. In this chapter, the probability distribution of the PSD at a given level of ground motion intensity, and the influence of the vertical earthquake component and various structural and ground motion characteristics on the PSD are investigated. Simplified equations for estimating the PSD are also developed for design purposes.
