2012, Agriculture, Ecosystems and Environment (151) 1-5
Birds, lizards and insects were surveyed in three sun and three shade coffee plantations in Puerto Rico to provide a comprehensive comparison of biodiversity between plantations types and to identify potential interrelationships (e.g., biological or natural control services) between members of each taxon and coffee pests. Abundance of avian species,...
Significance of rotating ground motions on nonlinear behavior of symmetric and asymmetric buildings in near fault sites
Erol Kalkan, Juan Carlos Reyes
2012, Book
Building codes in the U.S. require at least two horizontal ground motion components for three-dimensional (3D) response history analysis (RHA) of structures. For sites within 5 km of an active fault, these records should be rotated to fault-normal/fault-parallel (FN/FP) directions, and two RHA analyses should be performed separately (when FN...
