Seismic Performance Analysis of Lightweight Aggregate Concrete (LWAC) Frame Column
摘要
A three-dimensional model of LWAC frame column was established, and numerical simulations were conducted using ABAQUS under horizontal low-cycle reversed loading. The results indicate that LWAC frame column exhibits shear failure under low-cycle reversed loading. Despite having lower bearing capacity, a smaller ductility coefficient, and reduced interlayer displacement angle compared to normal concrete, LWAC still meets seismic design code requirements and demonstrates good deformation capacity.
