Abstract

Concrete vaults of the Late Classic Maya complex of Bonampak, Chiapas, Mexico (580-800 C.E.) are well-preserved examples of the one-story, corbelled style of the Maya and they house some of the best examples of murals in the Americas. To assess the monuments in light of the seismic risk of the region and the structures’ cultural value, the present work compares sectional finite element (FE) models of Structures 1 and 3 to the lateral capacities produced using kinematic limit analysis (KLA). A sensitivity analysis of the model’s tensile strength shows that as material strength approaches zero, FE analyses converge to the lateral capacities defined using KLA. Modelling is performed in Abaqus/CAE Explicit, which allows for large deformations without numerical failure. The concrete damaged plasticity (CDP) formulation is adopted for Maya concrete. This paper illustrates that the results of KLA are conservative estimates for lateral capacity and that the presence of non-zero tensile strength may significantly increase lateral capacity. Further 3D analysis reinforces the validity of these claims and the FE approach.
