A new empirical formulation for the out-of-plane resistance of infilled reinforced concrete frames without prior in-plane loading

Abstract

The paper presents a new empirical expression estimating the out-of-plane (OOP) resistance of infilled reinforced concrete frames subject to horizontal forces. The new model is calibrated through an optimization process based on a hybrid dataset.

Highlights

  • A new empirical formulation for the evaluation of the out-of-plane resistance of masonry infills is presented.
  • The formula is based on a hybrid dataset made of real experimental tests and refined numerical simulations.
  • The new formula takes into account the effect of vertical loads on the out-of-plane resistance of infills.
