About this book

This book systematically presents these findings for the first time, focusing on the composition, force mode, structural characteristics, performance advantages, and calculation methods for each new structural system, and comparing each one with traditional structural systems.
In view of the persistent problems in the current equivalent cast in situ precast concrete structural systems and the development of non-equivalent cast in situ precast concrete structure systems, Southeast University and Harbin Institute of Technology have conducted extensive research and proposed several new types of precast concrete structural systems. Their findings in this regard can promote the development of basic theories and technologies for building industrialization, accelerate the advancement of China's building industrialization, promote the application of precast building technology, and realize the concept of green building.

Chapter 1. Introduction
Abstract
Building industrialization is widely comprehended as a new mode of production integrating design, production, construction, and other sustainable developments of the entire construction industry chain. It is the major direction to upgrade the construction industry in China. The development of precast/prefabricated building structures is the key part of building industrialization. In this chapter, firstly, the essential advantages of prefabricated constructions are summarized. Secondly, prefabricated concrete structures are categorized into several major types (including frame, shear wall, and frame-shear wall system) and then minor types within each major type, with comprehensive illustration and discussion. Thirdly, several well-applied systems, as well as their key technologies and representative cases, are introduced. Lastly, the limitations of the current prefabricated concrete structure systems are discussed, mainly from the perspective of the currently prevailing wet connections and the gradually emerging dry connections. The necessity to deeply study the “nonequivalent cast-in-place” prefabricated concrete structure system is pointed out.

Chapter 2. Ductile Precast Concrete Frame with Dry-Connections
Abstract
The chapter deals with the dry-connection methods for the precast concrete frame. The emulative cast-in-situ method and dry connection method are compared. The construction and mechanical principle of the replaceable energy dissipation connectors are introduced. Two types of dry-connection beam-column joints and a kind of column base are proposed and experimentally analyzed, respectively. In the end, the design method of dry-connected precast concrete frame based on the replaceable energy dissipation connectors is presented, focusing on the seismic performance and the design procedure. The proposed dry-connected precast concrete frames can be applied in high seismic regions, while the robustness and post-earthquake repair can be conveniently achieved.

Chapter 3. Prestressed Precast Concrete Frame with External Dissipaters
Abstract
This chapter deals with the subject of Prestressed Precast Concrete Frame with External Dissipators, such a precast concrete frame consists of non-emulative connections where precast frame members are connected with post-tensioned tendons and externally mounted dissipators. The external dissipators provide additional reinforcing and damper, improving the energy dissipation of the proposed self-centering prefabricated system. This chapter also presents the development of all-steel fuse-type dissipators and evaluates the hysteresis behavior of precast post-tensioned frame connections. Additionally, previous research is introduced in terms of the configuration of fuse-type dissipators, characterizing experiments, theoretical studies, and component tests, providing theoretical and technical support for the promotion and application of prestressed precast concrete frames with external dissipators.

Chapter 4. Friction Damped Self-Centering Precast Concrete Frame
Abstract
In this chapter, the seismic performance of self-centering precast concrete structures is discussed at the node and structure levels. A novel energy dissipator employing non-asbestos organic material which provides stable energy dissipation capacity has recently been developed for controlled ductile structures, and the effects of different loading history, loading rating and bolt torque on the energy dissipator are analyzed from quasi-static axial tests. The seismic response evaluation of self-centering prestressed concrete frames with infill walls (SCPC-IW frames) is presented, while three types of infill walls with different load capacity are selected to be installed in a bare self-centering prestressed concrete frame (SCPC Bare frame). Beam web friction devices are included in the beam-column connections to provide energy dissipation capacity. Numerical models of the SCPC frame, and the three SCPC-IW frames are established and analyzed in a finite element software, OpenSees. The nonlinear static analyses and nonlinear dynamic analyses under 44 ground motions are performed. The incremental dynamic analyses (IDAs), seismic fragility analyses, and collapse resistance capacity evaluation have also been conducted. The results show that the SCPC system has superior seismic resilience.

Chapter 5. Cast-In-Place Frame-Prefabricated Sub-Frame System
Abstract
This chapter studies the cast-in-place frame-prefabricated sub-frame system. Seismic isolation, energy dissipation technology, and primary-secondary structure system are adopted to reduce the seismic demand of prefabricated secondary frames, improve the energy dissipation capacity of the whole structure, and ensure the seismic safety of the structure.

Chapter 6. Prefabricated Rocking Wall Structural System
Abstract
Prefabricated rocking wall structural system has the features of low seismic damage and quick energy dissipation, harnessing the unique response pattern of rocking. In this chapter, a new type of damage-controllable rocking wall system is proposed. The system consists of multiple walls embedded inside a frame structure, with the prestressed tendon providing the self-resetting feature, replaceable damping blocks between walls providing energy dissipation, and dry contact surfaces lowering residual deformation. Firstly, both the monotonic and cyclic responses are investigated theoretically. Secondly, quasi-static experiments are conducted using large-scale specimens. Thirdly, finite element simulations are carried out. The results show that the proposed system experiences efficient dissipation, low structural damage, and low residual displacement when subjected to earthquakes.

Chapter 7. Prefabricated Concrete Cassette Structure
Abstract
This chapter proposed the components, behavior, and practical applications of a novel large-span structure called cassette structure. Composed of open-web sandwich slabs and grid frame walls, the cassette structure can reach over 30 m spans with only a floor system height of 1–1.5 m, much lower than current frame structures, and shows a good seismic performance. The test results of the open-web sandwich slab and grid frame wall were discussed, and the entire structural performances of the cassette structure under earthquakes were analyzed and assessed based on the test results.

Chapter 8. Modularized Suspended Building Structure
Abstract
This chapter introduces modularized suspended building structures, which can be categorized as mega-sub control configurations with precast/prefabricated components. Intrinsic seismic attenuation mechanisms of passive-control suspended buildings are illustrated mainly from the perspective of a large-mass-ratio TMD-structure system. The structural features of prefabricated modular structures are summarized before modularization of the secondary structure within the suspended building is proposed to induce a harmless pattern of secondary-structure-inter-story drift. Shake-table experiments are also conducted. The results of those investigations show that the modularized suspended building has a satisfactory multi-mode tuning effect induced by the aforementioned inter-story drift pattern, and thus an enhanced seismic control performance.
