Chapter 1 - Types of Structures and Loads

 

Semester Overview   STRUCTURAL ENGINEERING  The process of molding materials we can't really characterize into shapes we can't really analyze to withstand forces we can't really assess in such a way that the public doesn't really understand.  -- Eric H. Brown   Chapter Topic 1 terminology 2-5 statics 6 influence lines 8-9 deflections 10-12 indeterminate structures       8: integration, conjugate beam   9: energy (virtual work) 10: force method superposition tables conjugate beam virtual work (integrals) solve for forces and moments 11: slope-deflection write formulas sum moments solve for moment values 12: moment distribution table approximations solve for moment values

Objectives Identify common structural elements. Identify common types of structures. Calculate dead loads in load/area, load/length, and load units. Calculate live loads based on building function. Calculate column loads. Determine column's tributary area. Calculate wind loads on signs and buildings. Calculate snow loads on buildings.

Concepts   1. introduction 2. classification of structures     - structural elements     - types of structures 3. loads     - dead loads     - lives loads 4. structural design

Terms γ = specific weight (lb/ft3) p = pressure (lb/ft2) = thickness × γ w = distributed load (lb/ft) = area × γ W = weight (lb) = volume × γ DL = dead load LL = live load reduced live load importance factor
