This paper, highlighted on knowledge about engineering properties and development of mix design nomograph of concrete containing PET wastes. 2.
The mix design nomograph developed can help field engineers select the proper mix proportion parameters to meet specified concrete performance criteria.

The buckling resistance moment for Channels or I section in BS 5950: parts is therefore (8) Cb= 1.75 – 1.05 β+ 0.3β2 £ 2.3 (9) Experimental Investigation In order to investigate the (Lateral Flexural – Torsion Buckling) buckling and ultimate strength behavior of CFS lipped channel beams used as flexural members, a full scale bending test rig was designed, fabricated and built in the GCT structural dynamics Engineering Laboratory.
It is the matter of engineering judgement as to how the effective length should be used in different Circumstances.

The well-known original rigid pavement design equation is as follows: (1) To serve the needs of predicting pavement serviceability index (PSI) after certain load applications on a given section, it is not uncommon that engineers would rearrange the original rigid pavement equation into the following form: (2) Lee [9] has pointed out that a regression model is very different from a mathematical equation in that the latter one may be transformed or rearranged in various forms without losing its generality.
