摘要

This study focuses on the development and implementation of a layered analysis method for predicting the response of FRP-reinforced glulam beams with partially composite concrete decks. The development of the model is quite general, allowing the easy incorporation of material nonlinearity and nonlinear load-slip response of wood-concrete connectors. An effective numerical algorithm is developed and implemented for solving the governing integral and differential equations, which relies on Newton's method and a single level of iteration. The model is verified through comparison with published experimental data on the bending response of partially composite wood-concrete beams. References: 27
