31、te shear walls (SPW) have been used in a signi- cant number of buildings, beginning decades ago, before the existence of design requirements specically address- ing this structural system. Implementation has accelerated signicantly since the recent publication of various design standards, specicatio

32、ns, and other guidelines providing design requirements in both high-seismic applications and wind and low-seismic applications (as will be reviewed in subsequent chapters). 1.1.1. Overview This introduction provides a general description of steel plate shear walls (SPW) and the Special Plate Shear W

33、all (SPSW) system. This introduction also describes the format and organization of the Design Guide. This Design Guide has been developed using: ASCE 7-05 Minimum Design Loads for Buildings and Other Structures, including Supplement No. 1 AISC 360-05 Specication for Structural Steel Buildings AISC 3

34、41-05 Seismic Provisions for Structural Steel Buildings, including Supplement No. 1 Analytical and capacity-design methods presented in this Design Guide typically establish the seismic load effect on a member or connection; this load effect can be utilized in ei- ther LRFD or ASD load combinations.

35、 The design examples in this Design Guide illustrate the LRFD method. The Design Guide addresses design for both high-seismic applications and wind and low-seismic applications. Certain provisions of AISC 341 are used regardless of the Seismic Design Category. Throughout this Design Guide, standards

36、 are referred to by their number (e.g., ASCE 7, AISC 360, AISC 341, etc.). The document titles are listed in the bibliography. 1.1.2. Wall Types Steel plate shear walls in building construction are of various types. By far the most popular in the United States is the unstiffened, slender-web steel p

37、late shear wall. This type is the basis for the SPSW system, which is included as a “Basic Seismic Force Resisting System” in ASCE 7 and AISC 341. This type of web plate has negligible compression strength and thus, shear buckling occurs at low levels of loading. Lat- eral loads are resisted through

38、 diagonal tension in the web plate 1(akin to tension-eld action in a plate girder), rather than in shear. Boundary elements are designed to permit the web plates to develop signicant diagonal tension; for high- seismic design, they are designed to permit the web plates to reach their expected yield

39、stress across the entire panel. Stiffened web plates may also be used. Stiffening increas- es the shear-buckling strength of the web plate. Sufcient stiffening to permit the web plate to develop its shear yield strength may be added, or the stiffening may be partial. For partially stiffened web plat

40、es, the strength is a combination of the shear buckling strength and the additional strength gained from tension-eld action. This available strength is calculated using methods developed for plate girders, as dis- cussed in Chapter 3. Composite steel plate shear walls have also been used in building

41、 design. In this system, steel web plates are stiffened by adding concrete on one or both sides of the web plate. Sufcient stiffening is typically provided to permit shear yielding of the web plate. Chapter 3 contains a treatment of composite steel plate shear walls, including the requirements of AI

42、SC 341. Stiffening of the web plate has a moderate effect on the strength and stiffness of the wall. Additionally, it tends to reduce the exural strength and stiffness required of the boundary elements. Stiffening of the web plates also re- sults in hysteretic behavior that is signicantly less pinch

43、ed. However, it also substantially increases the cost of the con- struction and increases the thickness of the wall. It is gener- ally preferred to achieve the required strength and stiffness by utilizing an unstiffened, slender web plate, rather than a stiffened web plate. Very high strength and st

44、iffness can be provided by unstiffened steel web plates of moderate thick- ness. In high-seismic design, the hysteretic behavior can be improved with the use of rigid beam-to-column connections in the frame of the shear wall. Steel plate shear walls with unstiffened, slender web plates are the focus

45、 of this Design Guide. Chapter 3 con- tains a design method for this type of steel plate shear wall. Chapter 1 History of Steel Plate Shear Walls 1 The term web plate is used to refer to the steel plate that resists the horizontal shear in the wall. A web plate connects to columns, called Vertical B

46、oundary Elements (VBE), on either side, and beams, called Horizontal Boundary Elements (HBE), above and below.2 / DESIGN GUIDE 20 / STEEL PLATE SHEAR WALLS (a) (b) Fig. 11.

48、 low-seismic application, and Chapter 5 uses this system in a design example for high-seismic application. Chapter 6 ad- dresses the design of openings in steel plate shear walls with unstiffened, slender web plates. 1.1.3. Applications Steel plate shear walls have been used in a large number of bui

49、ldings, including in the United States, Canada, Mexico, and Japan. Building types have ranged from single-family residential to high-rise construction. In addition to new con- struction, steel web plates have been added to retrot existing frame buildings requiring additional strength and stiffness. SPSW may be used wherever the building function per- mits walls of moderate length. Mid-rise and high-rise con- struction, with their repetitive oor plans and continuous building core, are especially well suited for SPSW. Chapter 1 contains an extensive list of buildi
