1. 1. Dynamic Performance of a Tall Building to Earthquake Loading : Finding the optimum mass and stiffness

   University essay from KTH/Bro- och stålbyggnad

   Author : Andrés Alonso San Segundo; [2022]
   Keywords : ;

   Abstract : With the increasing cost of land, the development of ultra-high performance concrete, and the technological advancements in equipment and machinery, we are able to construct and refurbish skyscrapers like never before. How they are built, what materials they use, or what structural system defines them, all affect their dynamic response, which in the end is the combination of the stiffness and mass, two key parameters in engineering of tall buildings.
