摘要：
A Finite Particle Method (FPM) based on vector mechanics is proposed. Utilizing the new structural analysis method, the framework of the seismic progressive collapse analysis of single-layer reticulated domes is performed by taking the geometric nonlinearity, material nonlinearity, and member fracture into account. The theoretical fundamentals of the FPM are derived. The method and algorithm to handle nonlinearities and member fracture are developed. The direct input method is adopted to consider seismic actions. The whole seismic progressive collapse procedure for a single-layer reticulated dome is simulated using self-coded programs. The effects of rise-span ratios on the anti-collapse performance of single-layer reticulated domes are investigated. The collapse times and modes are also discussed. Local strengthening is used in the anti-collapse design of a single- layer reticulated dome based on different collapse modes of space domes. © 2016, Engineering Mechanics Press. All right reserved.
