AStrutTie 2017 – The powerful software for structural design
HanGil IT develops AStrutTie 2017, a software that can be used for strut-tie model analysis and design for concrete members having disturbed stress region(s).
This software facilitates the construction professionals to design corbel (bracket), abutment/pier footing, bridge pier coping (pier cap), frame corner, anchorage zone, deep beam, etc. The software is compatible with U.S (ACI 318, AASHTO LRFD) and Europe (EuroCode 2) codes and specifications.
A concrete member is segregated into B-region(s) and D-region(s). D-regions stand for the portions of structure where the strain distribution is extremely nonlinear. Empirical approaches are followed for most design practices for D-regions.
The strut-tie model is suitable to understand load transfer mechanisms and structural behavior in an efficient manner and it enhance the capability of the designers to deal with unconventional circumstances along with D-regions.
The most accurate strut-tie models is developed based on the principal stress flows and/or evolutionary structural optimization (ESO) results. A specialized solver is connected that has the ability to deal with any types of internally/externally (in)determinate strut-tie models. The strut-tie model provisions of ACI 318-14 (2014), AASHTO LRFD (2014), and EC2 (2004) are employed.
In order to design the strut-tie model rapidly and easily, multirole templates are arranged for corbel (bracket), abutment footing, pier footing, bridge pier coping (pier cap), frame corner, anchorage zones together with inclined and straight tendons, and deep beams with concentrated and distributed loads.
The shapes of concrete members and truss models are also formed by importing .dxf files. Advanced element sets illustrate truss mechanism, truss and arch mechanism, and fan action is arranged.
AStrutTie offers several automated design checks concerning the conditions for rebar requirement and strength verification of struts and nodal zones.
Visual verifications of strength conditions can also be performed. A structural design report is created automatically, and design results are evaluated by previewing the report. The structural design report is printed as a .rtf or .xlsx file format.
