• structural elements that resist excessive
  • deflection
  • deformation

Introduction 10Lecture 1

Relation to Architecture

“The geometry and arrangement of the load-bearing members, the use of materials, and the crafting of joints all represent opportunities for buildings to express themselves. The best buildings are not designed by architects who after resolving the formal and spatial issues, simply ask the structural engineer to make sure it doesn’t fall down.” - Onouye & Kane Statics and Strength of Materials for Architecture and Building Construction
