Loads on Structures – Part 1 TED 316 – Structural Design
Dead loads • Live loads • Dynamic loads • Environmental loads • Other loads Types of loads
Relatively constant over time • Weight of structure • Weight of immovable fixtures such as walls, carpets, cabinets, etc. • Aka Permanent loads Dead load Dead load
Temporary, short duration, or moving loads Dynamic loads, may involve considerations such as impact, momentum, vibration, slosh dynamics of fluids, fatigue Change relatively slowly Include all forces that are variable within the normal life cycle not including construction or environment Imposed load Live loads
Change value rapidly or abruptly Gust of wind or dropped object on floor May be dangerous or catastrophic if they exceed load capacities of structure Many times the load of a slowly applied force Can be a static or dynamic load Period of building oscillations Dynamic loads
Act as a result of: Weather, Typography, Natural phenomena • Wind loads • Snow, rain and ice loads • Seismic loads • Ponding loads • Loads from fluids or floods • Dust loads • Lateral pressure of soil, ground water or bulk materials Live snow load • Temperature changes leading to thermal expansion cause thermal loads Environmental loads
Support settlement or displacement Fire Corrosion Explosion Creep or shrinkage Impact from vehicles or machinery Loads during construction Other loads
