The aim of this study is to investigate the behavior of RC concrete beams reinforced with basalt, carbon, glass fiber reinforced polymer bars and conventional steel. A comparison between the results has been performed to investigate and study the effect of fire on reinforced concrete beams considering the following items: (flexural capacity, deflection behavior and crack pattern). It is noticeable that the use of FRP bars significantly increased the ultimate load of the specimens, where the percentage of increase ranged between 34 - 73 % of the ultimate load of the specimen C-S under static load. The greatest ultimate load was reached the beam that was reinforced with carbon bars (CFRP). It was also noticed able that the use of FRP rods significantly increases the deflection of the beams. The percentage of increase was between 45 - 170 % of the final deflection of the C-S specimen under static load. It was noted that the effect of the fire on the beams reinforced with fiber bars (FRP), where the efficiency of bearing capacity of beams after fire decreases by 11 to 18 % of the actual efficiency of bearing capacity of beams control. As for the beam reinforced with conventional steel bars, its efficiency was reduced by 15 % from the actual capacity.
Cash flow is considered to be the main acceleration’s factor of any construction contract, which has a large and direct impact on projects completion dates as well as the project contractual duration. This is very evident when examining how the owners benefit from their projects in achieving or forfeiting the desired economic feasibility determined in the feasibility study of any project.It is noted that the cash flow plan is issued through a Critical Path Method (CPM) for a project which entails only an estimate of the monetary value of the construction work to be carried out on site and on a rough and approximate basis using the cash flow’s curve (S-CURVE), which is usually gives a different value from the actual work performed onsite.The impact of this problem on financial management for any project is as follows:In the case of underestimation, if the available estimates are less than the required cash flow, it is considered as a major cause for delay in project completion as well as the inability of the owner to achieve the economic feasibility Internal Rate of Return (IRR) required for the project. Also, this leads to monitory error due to the financial compensations due to the contractor as a result of the damage caused by time extensions due to the holdings of the cash entitlements.In the case of overestimation of the value of the required cash flow with a high margin of error, this leads to the monetary waste of amounts that could have been invested in other ventures, projects or opportunities.This paper provides a summary of the importance of determining the appropriate amount of cash flows required to be provided by the owner’s financial management, which leads to achieving the appropriate projects financial management gains and thus reducing financial losses or disputes in construction projects in the State of Kuwait.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
