Evaluation of horizontal loads in the concept design of tall building concrete structures

Horizontal forces, both from wind and seismic actions, govern in most cases the structural design of tall buildings. An accurate assessment magnitude horizontal actions initial project stages provides a valuable information for typology choice preliminary sizing members. This study develops analytical evaluation forces considering dynamic effects this type buildings to be applied stages. The research uses methods based on current codes standards together with numerical Finite Element models graphic tools that provide set original data benchmark case-study. It includes sensitivity analysis shows influence some parameters have, such as damping structure, forces. new visual method two complex importance against seism is shown while building stiffness decreases increase transversal actions.
