The Seismic Behavior Of Multistory Frame Structures

CHAPTER 2 LITERATURE REVIEW 2.1 INTRODUCTION The seismic behavior of multistory frame structures has been studied extensively in the last few decades due to their efficiency as earthquake resisting systems. The multistory framed systems can be categorized as reinforced concrete (RC) frames, masonry-inï ¬ lled frames, and wall-frame system. The literature survey in this chapter highlights some of the previous experimental and analytical Work done on the seismic performance of existing and rehabilitated structures. The survey covers retrofitting and analytical models of different structural systems, namely: RC frame structures, RC structural Walls, FRP confined beams and columns, rehabilitated frames using FRP bracings, rehabilitated frames using steel bracing and masonry-inï ¬ lled frames. 2.2 NONLINEAR MODELS Several analytical models for the non-linear analysis of reinforced concrete structural components have been proposed. These range from very refined and complex finite element models (N go and Scordelis I967) to simplified macro-models (Chen and Powell 1982, Lai et al, 1984, Powell and Campbell 1994, Pctrangeli et al. l999). Refined analytical models are typically used in predicting the response of small structures or structural subassemblies. The use of refined finite element models in non-linear static, cyclic and dynamic response of reinforced concrete frames is complex, time consuming and may not be practical. On the other hand, simplified macro-models have beenShow MoreRelatedManaging Information Technology (7th Edition)239873 Words   |  960 Pages9 ̈ CASE STUDY 1 Midsouth Chamber of Commerce (A): The Role of the Operating Manager in Information Systems 10 PART I Information Technology Chapter 2 Computer Systems 17 19 Basic Components of Computer Systems 20 Underlying Structure 20 Input/Output 20 Computer Memory 21 Arithmetic/Logical Unit Computer Files Control Unit 23 23 25 The Stored-Program Concept 25 Types of Computer Systems 28 Microcomputers 29 Midrange Systems 30 Mainframe Computers
