The Wood–Armer method is a structural analysis method based on finite element analysis used to design the reinforcement for concrete slabs. [1] This method provides simple equations to design a concrete slab based on the output from a finite element analysis software.
Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel-reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving (see below). [1] [2]
The automatic clash detection identified several clashes that were missed by the subcontractors, who were performing this task manually. Also, the manual clash detection identified clashes which could not possibly be found by the automatic clash detection software, since one of the clashing objects (e.g. cable trays) was not modeled in the BIM.
A slab-trap is very much alike but more conclusive. Hunting with slabs is a system of hunting by means of a slab-trap. The fundamental part of the device is a slab. Preparing this trap was a delicate task. [7] [13] [14] Preparation of the trap: A slab of suitable dimensions is held in a raised position forming an appropriate angle with the ...
To this design Australian settlers often added a verandah. [44] Most slab-hut construction techniques could be described as bush carpentry. Few early settlers could afford the time, or possessed the capital, to build any dwelling more impressive than a slab hut: they had first to clear their land and get a crop planted or pasture fenced. [45]
Idealisation of arching action forces in laterally restrained slab. Arching or compressive membrane action (CMA) in reinforced concrete slabs occurs as a result of the great difference between the tensile and compressive strength of concrete. Cracking of the concrete causes a migration of the neutral axis which is accompanied by in-plane ...
All voided biaxial slabs incorporate an array of rigid void formers which contain air within the voids. These void formers are most commonly made of plastic such as high-density polyethylene, and may use recycled materials. [7] The void formers are produced in a variety of shapes depending on the design of the slab.
