Genetic algorithms for assigning tasks to construction machine operators / Genetski algoritmi za rasporedivanje rukovatelja gradevinskih strojeva
(Croatian Association of Civil Engineers, 2011)
The authors describe the methodology for using genetic algorithms in solving problems of optimum assignment of tasks to construction machinery operators, aimed at achieving maximum efficiency. A special emphasis is placed ...
Identification of flutter derivatives by forced vibration tests
(Union of Croatian Civil Engineers and Technicians, 2017)
Results of an experimental study related to flutter phenomenon are presented in the paper. Two cross-sections are considered: a rectangular cross-section and a typical symmetric bridge cross-section. Stationary coefficients ...
Fire-resistance prognostic model for reinforced concrete columns
(Croatian Association of Civil Engineers, 2012)
The prediction model used for defining fire resistance of reinforced concrete columns exposed to standard fire from all four sides is presented in the paper. The proposed model relies on the concept of artificial neural ...
Testing heuristic optimisation methods for vibration-based detection of damage
(Union of Croatian Civil Engineers and Technicians, 2016)
Considerable efforts have been made in recent years for the development of non-destructive techniques for detection of structural damage based on changes of dynamic parameters of structures. The tests are made on a model ...
Stabilization of fine-grained soils with fly ash
(Union of Croatian Civil Engineers and Technicians, 2015)
Results of laboratory research focusing on soil stabilization, using fly ash without activators, are presented in the paper. Two types of fine-grained soils were tested: low to medium plasticity clay and very expansive, ...
Analysis of cracking on running surface of rails
(Croatian Association of Civil Engineers, 2013)
The problem of cracking at the rolling surface of rails is considered in the paper. This damage to the rolling surface of rails, known as "squat", may lead to disintegration of rail head in the length of 1 m or more. In ...
Application of artificial neural networks for hydrological modelling in karst
(Union of Croatian Civil Engineers and Technicians, 2018)
The possibility of short-term water flow forecasting in a karst region is presented in this paper. Four state-of-the-art machine learning algorithms are used for the one day ahead forecasting: multi-layer perceptron neural ...
Evaluation of methods for predicting axial capacity of jacked-in and driven piles in cohesive soils
(Union of Croatian Civil Engineers and Technicians, 2018)
This paper presents the evaluation of methods for predicting the ultimate axial bearing capacity of single piles based on the cone penetration test (CPT) results, and the evaluation of static methods based on the effective ...
Shear connection with groups of headed studs
(Union of Croatian Civil Engineers and Technicians, 2017)
The behaviour and characteristics of the elements of prefabricated composite steel and concrete structures are determined by behaviour of the longitudinal shear connection. Headed studs in groups are most frequently used ...
Use of finite element method for 2D and 3D analyses of tunnelling induced settlements
(Croatian Association of Civil Engineers, 2020)
Results of a series of 3D and 2D analyses of open-face tunnelling in marly-clayey deposits are presented in the paper. A parametric study was performed to investigate the influence of initial stress state, soil deformability, ...
