• Abstract:

  A comparative study based on experimental results of masonry wallettes
  subjected at vertical compression for various loading rates is herein presented.
  The specimens were made with general purpose mortar and two material groups:
  dense and lightweight concrete blocks. The loading rates were established as
  moderated (according to Mexican Regulations), slow (50% slower than the
  moderated rate) and fast (50% faster than the moderated rate). The presented
  results are mean compressive stress-strain relationships from three specimens
  tested at the same rate. The main individual properties of mortar and blocks were
  also investigated. This investigation shows that the compressive strength can
  vary about 11% among the group of specimens made of normal concrete blocks
  tested at different rates, meanwhile this variation of the wallettes made of
  lightweight concrete blocks is approximately 11.24%. Therefore, this change in
  the compressive strength of masonry structures needs to be considered when
  designing future masonry structures.
