Time savings earned by the possibility of the multiple connection imports and synchronization of models changed in ETABS can add a decisive advantage for your projects. Thanks to it, you can deliver your designs faster, more efficiently but still with the main focus on safety.
Hi all, I am a bit slow today, but this has been bothering me quite a bit this morning. I am modeling a cantilever beam in etabs, with one end of my beam fully moment connected (with no releases). This makes perfect sense to me, however the other end I have just moment released (as if it were pin connected). Is this correct? Shouldn't it be fully free, do I release the other end entirely to properly model this? I am kind of stumped here and was hoping someone could help out.
ETABS accepts IFC, CIS/2 and IGES data but I cannot get any of these to work - maybe this is a problem with the settings inside SM? Has anyone used ISM to transfer data between a non Bentley analysis programme?
This paper examines the optimal placement, optimal numbers, and the optimal shape of Buckling Restrained Braces (BRB) for a 3D shear-wall frame building structure based on linear static analysis utilizing ETABS software. The total amount of BRBs referred to as the number of BRBs are considered as design variables and the objective function to be minimized is the maximum story displacement and inter-story drift. The diagonal shape (D), X-shape (X), V-shape (V), and Inverted V-shape (Inv-V) of BRBs are installed between shear walls simultaneously with initial stiffnesses of 1K0, 2K0, 4K0, and 8K0, respectively. Then, the performance efficiency analysis is carried out to identify the effectiveness of initial stiffness, BRB shapes, and optimal stories. Based on the results of the optimization procedure and efficiency analysis, it is found that the performance of the structure can be improved by optimizing BRB placement within the optimal stories rather than using the maximum amount of BRBs in all stories. The most optimal location to install BRBs is the middle stories and the BRB placement at the upper and lower stories is shown to have minor or no effects on reducing story responses of the structure. Furthermore, the model with Inv-V, V, and X shapes of BRB have almost the same maximum efficiency performance, while the model with diagonal shapes has the lowest performance efficiency. Additionally, the maximum performance of the structure can be achieved by using larger initial stiffness. The proposed method is further validated by comparing the results of ETABS with MATLAB programming. It concludes that the method proposed in this study saves 40% of the total amount of BRBs used in the structure by optimal placement of BRBs within the height of the structure. This method of optimization allows the structural designer to decide the optimal placement, optimal shape, and optimal stiffness of BRBs either by the predetermined performance level of the structure or based on experiences in RC shear wall-frame building structures.
