摘要

在几种类型的楼板中，对于短跨度、中跨度和长跨度的结构，最具成本效益的楼板是不确定的。使用SAFE软件对4米、6米和8米跨度的实心、扁平、空心块(HB)和后张拉(PT)板的成本进行了比较。对于每个跨度长度，找到了混凝土和钢筋的总数量，并对4块板进行了比较。然后，将钢筋、混凝土、砌块、肌腱和模板的总成本制成表格并进行比较。结果表明:4、6m跨板的混凝土用量在HB板中最少，而8m跨板的混凝土用量在PT板中最少。4跨、6跨和8跨板的钢筋用量在PT板中最少。在经济方面，最具成本效益的选择是4m跨度的平板，与实心板，HB板和PT板相比，分别节省约14%，9%和17%。另一方面，对于6米和8米跨度，最具成本效益的选择是PT板，与实木、HB和平板相比，6米跨度的PT板分别节省了约10%、6%和6%，8米跨度的PT板分别节省了10%、20%和22%。因此，对于6米及以上的跨度，PT板可以显著节省成本。

Comparison of the post-tensioned, solid, hollow block, and flat slabs in terms of economy considering different span lengths

From among the several types of slabs, there is uncertainty about the most cost-effective one for structures with short, medium, and long spans. A study comparing the cost of the solid, flat, hollow block (HB), and post-tensioned (PT) slabs for 4, 6, and 8m spans was conducted using SAFE software. For each span length, the total quantities of concrete and steel bars were found and compared for 4 slabs. Then, the total cost of steel bars, concrete, blocks, tendons, and formwork was tabulated and compared. The findings revealed that the quantity of concrete in slabs with 4 and 6m spans is the least in the HB slabs, while for slabs with 8m spans, the quantity of concrete is the least in the PT slab. Besides, the quantity of steel bars in slabs with 4, 6, and 8 spans is the least in PT slabs. In terms of economy, the most cost-effective option is the flat slab for 4m spans, with savings of about 14, 9, and 17% compared to solid, HB, and PT slabs, respectively. On the other hand, for 6 and 8m spans, the most cost-effective option is the PT slab, with savings of about 10, 6, and 6% for the 6m span, and 10, 20, and 22% for 8m span compared to solid, HB, and flat slabs, respectively. Therefore, for 6m spans and more, PT slabs offer significant cost savings.
