Abstract
In order to optimize the cost of basement roof engineering,the mechanical properties and cost of floor were calculated by finite ele-ment nonlinear analysis method,and compared with the cost of unidirectional slab main and secondary beam floor.The results show that when the ratio of span to height is 6～8,the economic benefit of the axillary beam is the best.When the ratio of span to height is 6,the construction cost of axillary plate is the most reasonable.Compared with the axillary beam axillary slab floor per unit area,the total cost ratio of unidirec-tional slab main and secondary floor is increased by 7.2%.Therefore,the economic benefit of the axillary beam and axillary slab floor is more prominent,and it can be popularized and applied in the basement roof.关键词
