Book Description
This research investigates prefabricated light-gauge steel and concrete panels using reliable and commercially viable shear connectors. An analytical and experimental investigation was undertaken to study the flexural behaviour of light-gauge steel and concrete composite panels under uniform pressure. Normalweight and lightweight concrete panels were fabricated by embedding 16-gauge 41 mm x 203 mm steel channel sections (running parallel to each other) to a depth of 38 mm into a 64 mm thick concrete slab. Push-out tests were also conducted to evaluate the efficiency of three types of shear connection mechanism; natural surface bonding, predrilled holes, and punched holes. Only two types of shear connectors (predrilled holes and punched holes) were used in the full-scale panel specimens. Results show that the predrilled holes and punched holes provide full shear transfer between the steel and concrete. The ultimate load carrying capacity of the lightweight concrete panels exhibited similar behaviour to the normalweight concrete panels. All the panels exhibited good load carrying capacity and ductility, and satisfied the serviceability limit state of deflection. Thus, the proposed panels present a potential for a commercially viable composite floor system for building construction utilizing a maximum span of 2330 mm.

Book Description
The quality and testing of materials used in construction are covered by reference to the appropriate ASTM standard specifications. Welding of reinforcement is covered by reference to the appropriate AWS standard. Uses of the Code include adoption by reference in general building codes, and earlier editions have been widely used in this manner. The Code is written in a format that allows such reference without change to its language. Therefore, background details or suggestions for carrying out the requirements or intent of the Code portion cannot be included. The Commentary is provided for this purpose. Some of the considerations of the committee in developing the Code portion are discussed within the Commentary, with emphasis given to the explanation of new or revised provisions. Much of the research data referenced in preparing the Code is cited for the user desiring to study individual questions in greater detail. Other documents that provide suggestions for carrying out the requirements of the Code are also cited.

Book Description
A novel, light gauge steel stud-thin shell precast concrete panel system was developed to serve as a vertical wall panel element to resist vertical and out-of-plane horizontal loads. The behavior and capacity of this system to sustain in-plane lateral loads arising from wind and earthquake actions are currently not understood. The focus of this research is to assess the performance of such a system when subjected to lateral loading. Two-dimensional monotonic and reverse cyclic nonlinear finite element analyses of the Thin Shell Precast (TSP) panel was conducted using Program VecTor2. The analyses evaluated the effect of various components of the system including the type and size of the internal reinforcing bars and the influence of the exterior light-gauge steel framing. The modelling also shed light on the effect of reinforcement bonding and the difference in response between squat and slender wall systems. Through the nonlinear modelling, lateral load-displacement (drift) responses were generated for monotonic and reverse cyclic motions, in addition to quantifying the yield and ultimate loads and corresponding displacements (drifts). Preliminary analyses were used to modify the design of the Thin Shell Panel to achieve an improved lateral response.

Book Description
As software skills rise to the forefront of design concerns, the art of structural conceptualization is often minimized. Structural engineering, however, requires the marriage of artistic and intuitive designs with mathematical accuracy and detail. Computer analysis works to solidify and extend the creative idea or concept that might have started o

Abstract: "To ensure sufficient composite action to meet structural strength and stiffness requirements in precast concrete sandwich wall panels, the designer must provide adequate shear transfer between concrete wythes. In a typical sandwich panel, shear transfer may be provided through several different mechanisms. These mechanisms include: (1) solid concrete regions; (2) mechanical connectors that pass through the insulation wythe; and, (3) bond between the concrete wythes and the insulation. The objective to the work presented in this report is to investigate the flexural behavior of sandwich panels and the contribution to composite action provided by regions of solid concrete, wythe connectors, and bond. Tests were performed on four full-scale precast sandwich wall panels. A Prototype panel was tested, which included regions of solid concrete in the insulation wythe, metal wythe connectors, and no attempt was made to disrupt the bond between the concrete wythes and the insulation wythe. The degree of composite action developed by each of the different shear transfer mechanisms was then evaluated by testing three additional panels that included only one mechanism of shear transfer (solid concrete, wythe connectors, or bond). It was found that, for the panel geometries and materials treated in this study, the solid concrete regions provide most of the strength and stiffness that contribute to composite behavior. Steel M-tie connectors and bond between the insulation and concrete contribute relatively little to composite behavior. Therefore, for design purposes, it is recommended that solid concrete regions be proportioned to provide all of the required composite action in a precast sandwich wall panel. A precast concrete sandwich wall panel constructed similarly to the Prototype panel treated in this study will behave as a fully composite panel in terms of service load-deflection behavior and flexural strength."

Book Description
Steel frames are used in many commercial high-rise buildings, as well as industrial structures, such as ore mines and oilrigs. Enabling construction of ever lighter and safer structures, steel frames have become an important topic for engineers. This book, split into two parts covering advanced analysis and advanced design of steel frames, guides the reader from a broad array of frame elements through to advanced design methods such as deterministic, reliability, and system reliability design approaches. This book connects reliability evaluation of structural systems to advanced analysis of steel frames, and ensures that the steel frame design described is founded on system reliability. Important features of the this book include: fundamental equations governing the elastic and elasto-plastic equilibrium of beam, sheer-beam, column, joint-panel, and brace elements for steel frames; analysis of elastic buckling, elasto-plastic capacity and earthquake-excited behaviour of steel frames; background knowledge of more precise analysis and safer design of steel frames against gravity and wind, as well as key discussions on seismic analysis. theoretical treatments, followed by numerous examples and applications; a review of the evolution of structural design approaches, and reliability-based advanced analysis, followed by the methods and procedures for how to establish practical design formula. Advanced Design and Analysis of Steel Frames provides students, researchers, and engineers with an integrated examination of this core civil and structural engineering topic. The logical treatment of both advanced analysis followed by advanced design makes this an invaluable reference tool, comprising of reviews, methods, procedures, examples, and applications of steel frames in one complete volume.
