Özet

The Lattice Discrete Particle Model (LDPM) is used to simulate buckling deformation and study post-buckling strength of slender columns and thin Ultra-High Performance Concrete (UHP-FRC) plates. The LDPM computational framework can predict macroscopic behavior of concrete through mesoscale constitutive relationships where failure of the material is represented through fracture, cohesion in tension; and compaction, pore collapse in compression. Considering the proliferation of UHP-FRC with compressive strength similar to that of steel, improved tensile cracking resistance, post cracking strength, ductility, and energy absorption capacity, this research is a first step towards the exploration of thin-walled UHP-FRC concepts to deliver more durable and efficient structures. The simulation results indicate that LDPM can accurately predict the behavior of elastic and inelastic materials, including displacement-load deformation, buckling modes, post-buckling strength, and crack pattern and propagation.
