A waffle slab or two-way joist slab is a concrete slab made of reinforced concrete with concrete ribs running in two directions on its underside. [ 1] The name waffle comes from the grid pattern created by the reinforcing ribs. Waffle slabs are preferred for spans greater than 40 feet (12 m), as they are much stronger than flat slabs, flat ...
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] In many ...
Plackett–Burman designs are experimental designs presented in 1946 by Robin L. Plackett and J. P. Burman while working in the British Ministry of Supply. [1] Their goal was to find experimental designs for investigating the dependence of some measured quantity on a number of independent variables (factors), each taking L levels, in such a way as to minimize the variance of the estimates of ...
Slabs are one of the greatest consumers of concrete in many buildings, [14] so reducing the slab mass can make a relatively large difference to the environmental impact of a building's construction. Biaxial slabs may be marginally cheaper than solid slabs, partly due to the lower mass.
5 cm (2.0 in) Created. c. 1750 BC. Present location. British Museum, London. The complaint tablet to Ea-nāṣir ( UET V 81) [ 1] is a clay tablet that was sent to the ancient city-state Ur, written c. 1750 BCE. It is a complaint to a merchant named Ea-nāṣir, [ a] from a customer named Nanni. It is currently kept in the British Museum. [ 2]
Since the 1950s there have been several attempts to develop theories for arching action in both one and two-way slabs. One of the principal approaches to membrane action was that due to Park which has been used as a basis for many studies into arching action in slabs. Park's approach was based on rigid plastic slab strip theory, and required ...
Customer journey mapping is a design tool used to track customers' movements through different touchpoints with the business in question. It maps out the first encounters people may have with the brand and shows the different routes people can take through the different channels or marketing (e.g. online, television, magazine, newspaper).
