cost coparison beweeen formwark of solid and ribbed slab

Composite beam and slab. • Slimdek . • Long span cellular beams. • Reinforced concrete flat slab. • Post tensioned ribbed slab. Building B is typical of a prestige office building in central London, suitable for a company headquarters or similar high status function. It is a more complex structure than Building A, designed 

The BubbleDeck slab is a revolutionary biaxial concrete floor system developed in. Europe. High-density polyethylene hollow spheres replace the ineffective concrete in the center of the slab, thus decreasing the dead weight and increasing the efficiency of the floor. These biaxial slabs have many 

Comparison between Ribbed Slab Structure using Lightweight Foam Concrete and Solid Slab Structure using Normal Concrete . Furthermore, this software is able to calculate the raw cost and placement cost for the floor plan. 5. . of formwork for the bottom and the top was RM 1028.3 which is also considered a raw cost.

Which type of slab is the most cost effective alternative? conventional solid slab construction in an effort to reduce the weight of concrete .. slab thickness, in comparison to that of flat slabs, to merely the thickness necessary for enough strength to suspend loads between the beams. The span will obviously have a large 

solid slab. Hollow floor slabs, a product of modern designs, now require less reinforcement, less formwork and less concrete as a result of the holes, space, . Pots laid parallel to one another forms the rib in between them to receive reinforcement and concrete. The rib formed could be between 100mm - 150mm wide,.

waffle slab with solid heads, and the second is a waffle slab with band beams along column centerlines. Direct design method is used for the structural analysis and design of slabs. The cost function represents the cost of concrete, steel, and formwork for the slab. The design variables are taken as the effective depth of the 

Comparison between Ribbed Slab Structure using Lightweight Foam Concrete and Solid Slab Structure using Normal Concrete. Article · March Section and Distribution of Steel Bars on top and at the b. ottom of Ribbed Slab. The material costs for the concrete. (. volume. = 2.1. m. 3. ) and Formwork. (. area. = 41.3. m. 2. ).

Therefore, in waffle slabs, the areas between joists are kept empty or filled with lightweight material, which results in a reduction in the weight and cost of the slab. The formwork of a concrete slab is generally designed for the creation of proper support for fresh concrete before it can withstand itself. The formwork of concrete 

Keywords: Cost variation, Hollow slabs, Lagos state, Reinforced concrete, Solid slab, Waffle floor. 1. method of solid slab construction. Hollow floor slabs, a product of modern designs, now require less reinforcement, less formwork and less concrete as a result of the between formwork and hardening of concrete on site.

The use of flat slab building provides many advantages over conventional RC frame building in terms of architectural flexibility, use of space, easier formwork and shorter construction time. In the present work conventional and flat slab. B G 3 storey building is considered for cost comparison. The building is considered to 

The desire to construct a cost effective and safe building has also created many options for building components. For instant, there are different types of slabs like: solid slabs, hollow/ribbed slab, waffle slab, and flat slab. So how does Removal of formwork: This is done after 28days of curing. Advantages

work is to design R.C.C Beam Slab, One-Way Continuous Slab as well as Grid Slab for spans 15m X 27m and then compare the results. the cost of formwork and other accessories.Quantity of Table.1:“ Cost Comparison of R.C.C. One way continuous slab, Two way grid Slab and One way Ribbed Slab”. Figure 1: 

Waffle slabs have a thin topping slab and narrow ribs spanning in both directions between column heads or band beams. Flexible; Relatively light, therefore less foundation costs and longer spans are economic; Speed of construction; Fairly slim floor depths; Robustness; Excellent vibration control; Thermal mass; Good 

Furthermore cost comparison is made between the two systems of slab construction. For the 3.6 Analysis sheet for total cost of ribbed slab concrete. 57. 3.7. . Cost comparison. 35. 3.1.

struction of building slabs was the solid reinforced concrete slab. However, this slab required extensive formwork and falsework and had a high self-weight, making it unsuitable for today's re- quirements. A new slab system with precast lattice-reinforced joists began to be developed in Germany in the
