FEMA NATIONAL US&R RESPONSE SYSTEMSTRUCTURAL COLLAPSE TECHNICIAN TRAINING MANUAL 02-00 MODULE 1c STRUCTURAL ENGINEERING SYSTEMSPART 1. BUILDING MATERIALS & STRUCTURAL SYSTEMS SM 1c, 1&2 1In this introductory section our Objectives are as listed in theadjacent slides. We will quickly review the basics of how variousbuilding materials resist forces, the importance of Ductile behavior, the concepts of Vertical and Lateral LoadResisting SYSTEMS , and STRUCTURAL TYPESI ndividual LOADS, usually referred to as FORCES can be dividedinto four types: Tension. Compression, Bending, and When a FORCE is applied to an individual member, itproduces STRESSES, which are defined as the FORCE divided by the cross-sectional area on which it Example: If a 1000lb FORCE acting in Tension on a 2 inch x2 inch steel bar, will produces a 250 lbs per square inch (psi)Tension For simplicity we will we will discuss the effects of FORCES,and assume that the student understands the relationshipbetween FORCES and STRESSESTENSION FORCES stretch members of steel or wood.
and extreme loading ENABLING OBJECTIVES • Understand the Tension, Compression, Bending, and Shear Forces that are exerted on building materials, and how they behave. • Understand the concepts of Ductile andUnderstand the concepts of Ductile and Brittle behavior. • Introduce the concept of Vertical Load Path and Vertical Load Resisting Systems
