This book covers the materials to prepare the candidates for the Structural Systems Division of the Architect Registration Examination (A.R.E. 4.0). It includes the most up-to-date information based on the requirements provided by the National Council for Architectural Registration Boards (NCARB). The book consists of five parts: 1. General Structures, 2. Lateral Forces, 3. Structural Layout Vignette, 4. Questions and Answers, and 5. Appendix. The first two parts include a number of short numerical examples similar to those given on the A.R.E. The Lateral Forces section covers materials from the FEMA 454 publication on the earthquake resistant design, which the A.R.E. candidates must know. The book includes a large number of graphics to help explain the technical topics. The following is a brief description of each part of the book: General Structures - This part covers the general structures topics of the multiple-choice section of the A.R.E. It is divided into five main sections: 1. Structural Theory, 2. Steel Structures, 3. Concrete Structures, 4. Wood Structures, and 5. Long-Span Systems. Lateral Forces - This part covers the lateral forces topics of the multiple-choice section of the A.R.E. It is divided into four main sections: 1. Different Types of Lateral Loads, 2.
