Abstract
By the finite element method,this paper analyzes the response of glass fiber reinforced plastic mortar pipes under the earthquake loads in addition to standard static load.Considering the anisotropy of composite materials and the interactions between pipes and soil,the finite element model of buried FRPM pipe is established.First,the static loads are applied with a series of incremental load steps.Then,the seismic loading condition is simulated by specifying quasistatic displacements at the peripheral boundaries of the soil envelope to produce a shear-rackingdistortion equivalent to the maximum free-field seismic shear strain from the earthquake.Based on the above model,the response of different materials under earthquakes are compared and analyzed.Then,the influence of the following factors such as the diameter,the ring stiffness,and the depth of the FRPM pipe is studied.The result shows that the FRPM pipe has great potential for earthquake resistance with the designable characteristic and the ring stiffness,and the buried depth are important influence factors on seismic response.关键词
