Home Building in Haiti - Inadequate Lateral Load Resisting
Weighty concrete ceiling and floor slabs were made for hurricane weather. During an earthquake, the construction of most low-rise buildings meant the walls were dislodged and discharged. The confined masonry system should have worked well under those conditions, but, the frames built in Haiti were mostly inadequately designed and were not integrated enough with beams and columns that were reinforced. As a result, the walls do not have the in-plane load bearing capabilities necessary to withstands strong tremors.
