چکیده
Castellated steel beams (CSB) are an attractive option for the construction industry thanks to outstanding advantages, such as ability exceed large span, lightweight, and allowing flexible arrangement of technical pipes through beams. In addition, complex localized global failures characterizing these structural members have led researchers focus on development efficient design guidelines. This paper aims propose artificial neural network (ANN) model with optimal architecture predict load-carrying capacity CSB a scheme simple beam bearing load located at center beam. The ANN is built 9 input variables, which essential parameters equivalent geometrical properties mechanical material, overall depth castellated beam, vertical projection inclined side opening, web thickness, flange width, width post middepth, horizontal minimum yield stress, stress. output variable CSB. With [9-1-1] containing one hidden layer, performance evaluated based statistical criteria R2, RMSE, MAE. results show that highly effective predictor best value R2 = 0.989, RMSE 3.328, MAE 2.620 testing part. seems be algorithm machine learning predicting capacity.

Failure Load Prediction of Castellated Beams Using Artificial Neural Networks
This paper explores the use of artificial neural networks in predicting the failure load of castellated beams. 47 experimental data collected from the literature cover the simply supported beams with various modes of failure, under the action of either central single load, uniformly distributed load or two-point loads acting symmetrically with respect to the center line of the span. The data ar...
متن کاملLoad Carrying Capacity of Simply Supported Variable Thickness Circular Plates
The calculation of the load carrying capacity of variable thickness circular plates subjected to arbitrary rotational symmetric loading is presented. The analysis considers plate materials that obey either the square or the Tresca yield criterion. By using upper and lower bound theorems of limit analysis, corresponding estimations for the load carrying capacity of the plate are obtained. It is ...
متن کاملOptimal Trajectory of Flexible Manipulator with Maximum Load Carrying Capacity
In this paper, a new formulation along with numerical solution for the problem of finding a point-to-point trajectory with maximum load carrying capacities for flexible manipulators is proposed. For rigid manipulators, the major limiting factor in determining the Dynamic Load Carrying Capacity (DLCC) is the joint actuator capacity. The flexibility exhibited by light weight robots or by robots o...
متن کاملStepwise Regression for shear capacity assessment of steel fiber reinforced concrete beams
The addition of steel fibers into concrete improves the postcracking tensile strength of hardened concrete and hence significantly enhances the shear strength of reinforced concrete reinforced concrete beams. However, developing an accurate model for predicting the shear strength of steel fiber reinforced concrete (SFRC) beams is a challenging task as there are several parameters such as the co...
متن کاملLoad-carrying behaviour of steel-to-timber dowel connections
This paper details tests on steel-wood-steel connections with thin dowels carried out at the University of British Columbia in Vancouver, Canada. Connections configurations were selected in such a way that the influence of the main parameters such as dowel slenderness ratio, dowel strength, fastener spacing and end distance and the number of dowels could be studied. An important issue of the pa...
