Because of the competitive price and good mechanical characteristics, a jute–polyester FRP (JPFRP) hybrid confinement can be used in the strengthening of structures. To the best of our knowledge, no published literature about the behavior of circular and square concrete short columns confined with...
The manufacturing cost per 1 m3 of concrete was calculated using the unit price (Korean price information DB), based on the amount of materials and energy sources used in each step (Equation (12)). As shown in Table 6, the standard price information DB of Korea was investigated and ...

It is evident that for in-situ testing, the system used should be portable, with relatively low power thermal excitation system, low price and with relatively quick testing procedure. Looking at all these prerequisites, it should be noted that the power of excitation system is determined by the...
Introduction Civil structures are frequently constructed using concrete due to its several advantages including low price, high compressive strength, and good durability. However, in general, the structural integrity of reinforced concrete structures continuously declines with age, arising from concrete creep...
