Article
Full-text available
The purpose of this study is to develop a genetic algorithm (GA) based software that can perform resource allocation close to optimum and that can determine the critical path by minimizing the project duration according to the resource profile for a present work schedule and resource pool using a programmable objective function. In this context, th...

The analysis of a construction project, regarding cost, is one of the most vital problem in planning. Due to its nature, the construction sector is an area of strong competition and estimation works are of vital importance. In recent years the Turkish Republic has started a serious urban regeneration movement in parallel to its economic development...
Article
Turkish public procurement law and secondary regulations describe tender evaluation in detail. In this system, bidders’ capabilities on each qualification criteria are evaluated either as satisfied or not satisfied therefore final evaluation is solely price based. This method is criticized as incomplete and lacking consideration in terms of the con...

Concrete which is a composite material is one of the most important construction materials. Compressive strength is a commonly used parameter for the assessment of concrete quality. Accurate prediction of concrete compressive strength is an important issue. In this study, we utilized an experimental procedure for the assessment of concrete quality....

The California Bearing Ratio (CBR) test determines behaviour of road sub-base and granular layers for flexible pavement. In the conventional CBR test, compacted sample was waited in air for 24 h and in water for 4 days. In this study, the fresh and 28 days curing effects were examined and pH values were measured end of 28 days curing on the CBR per...

Today, a flow of refugee which has turned into the biggest problem of the happened towards various countries due to the disturbances emerged in the Middle East states headed particularly by Turkey. These refugees have failed to ensure the intercultural adaption in the countries where they have taken shelter. At the same time, the refugees are in po...

In this study, a fuzzy logic prediction model for compressive strength of concrete was developed based on various nondestructive tests, such as Windsor Probe Penetration Test, Ultrasonic Pulse Velocity and Schmidt Hammer. Experimental results of non-destructive tests were used to construct the fuzzy logic model. The obtained results with fuzzy logi...

In this study, usability of stone powders that are obtained from the wastes during the processing of Ahlat stone (ignimbrite) in concrete was investigated. For this purpose, Ahlat stone powder was used in 0, 5, 10, 15, 20, 25 % proportions. Concrete mortar samples were prepared by this way. In order to compare the performance of Ahlat stone powder,...

An important factor to consider is the resistance of load bearing masonry walls subjected to out-of-plane loading during an earthquake. In addition to in-plane forces, earthquake accelerations produce out-of-plane forces which may cause the wall to fail under flexure, very similar to a reinforced concrete slab, loaded perpendicular to its plane. Fo...

The seismic collapse of a low-rise unreinforced masonry (URM) building is initiated by the out-of-plane failure of walls at roof level. The theoretical basis of this engineering problem is presented. The available strength and ductility of a URM wall is presented, which was tested under reversed loads to simulate seismic effects. It was seen that b...

Concrete which is a composite material is one of the most important construction materials. For the improvement of concrete quality some advanced technologies are used for curing and placement of concrete. Vacuum processing is one of these technologies. With the vacuum application, water content of the mixture is decreased and by this way a better...
Article
In this study, effects of super plasticizer (SP) and curing conditions on properties of concrete with and without fiber were investigated. In the concrete mixtures, Portland cement, artificial aggregate, SP and steel fibers were used. SP in concrete mixtures was used with ratios of 1.0%, 1.5%, and 2.0% by weight of cement and so C25 concrete was pr...

In this study, the performance of some non-destructive tests for the determination of compressive strength of concrete was investigated. Windsor probe penetration test, Schmidt hammer test and Ultrasonic test which are non-destructive test methods were carried out on hardened concrete. Besides of non-destructive tests, compressive strength of concr...

In this study, silica fume (SF) was replaced with cement by the amount of 0, 2.5, 5 and 10 % in the steel fibre reinforced concrete. Concrete samples were produced by 0.50 water/cement (w/c) ratio according to C 25 and were compacted by means of table vibrator. Samples having 100×100×500 mm dimensions were produced and flexural strength test was ap...

In the scheduling of the resource-constrained projects, three scheduling methods are used. Heuristic method is one of them. In the programming of the projects which have high amount of activity number and resource number-such as construction investments-the heuristic methods are used in the work, 5 different housing estate projects are scheduled ac...
