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.
n Bending causes the bottoms of simple beams to become ... Example: A roll of coins is Sheared off as each coin slips past the other n This type of failure can be sudden. n Nail failures in wood structures, which involve some degree of pullout, can occur with enough deformation to …
