GSE General Structural Engineering


Concrete structural analysis and design software



Part of the GSE (General Structural Engineering) software, GSE CONCRETE allows the design of concrete members subjected to a linear, P-Delta, non-linear, seismic or dynamic analysis.
• Second order effects may be accounted for according to the simplified method of the design codes.
• Effects of lateral drift and internal member deformations may be considered together or independently.
• The program allows to design continuous members.
• Design of bending, shear, torsion and combined axial forces and bending.
• The program calculates all required reinforcement and development lengths.
• The program can design longitudinal reinforcement, stirrups and column rein forcement for common concrete section shapes.
State of the art technology built around the concept of physical members that allows to accurately design the reinforcement of continuous members such as beams and columns. The program can design a whole or only a part of the structure.

The GSE Concrete software supports the American ACI-318 code, the Canadian CSA-A23.3, the Egyptian code ECCS 203. Libraries for standard American, Canadian or Egyptian reinforcement bars.

It also allows to calculate the resistance of the elements once the reinforcement is known, which allows to improve the design of a structure or to evaluate the resistance of an existing one. Reinforcement bars and stirrups, applied loads, resistance curves and interaction diagrams are displayed graphically.
The GSE software allows the verification of concrete members subjected to a linear, P-Delta, non-linear, seismic, dynamic or moving load analysis. Verification of bending, shear, torsion and combined axial forces and bending.

Calculated reinforcement can be further edited and additional resistance verification calculations can be performed on the whole or selected parts of the structure. This cyclic design method allows to closely match practical user requirements without the need of tedious hand calculations. Reinforcement layouts, resistance curves and interaction diagrams are displayed graphically.

The program considers longitudinal reinforcement and bent bars for bending resistance. The program considers straight or inclined stirrups and bent bars for shear and torsion resistance. The program considers column reinforcement for combined axial and bending loads.
The soil-structure interaction is an important component in the design of a building or any structure in general. In order to improve productivity, the GSE software provides an automatic slab on grade generation function.

This function makes it possible to distribute the soil stiffness to the slabs modeled by finite elements by the means of equivalent springs. This allows for the complete analysis and design of slabs, using a 3D model as well as the reinforced concrete design tools from the SAFI GSE Concrete module. With this function, users can generate and efficiently analyze slabs of complex geometries.
The analysis of the model allows to calculate several important parameters for the design of the foundation. While considering the various load combinations, the nodal displacements of the slab on the ground make it possible to check the stability and deflections of the structure. According to the deflection, the stiffness and the tributary area calculated for each of the nodes, the exerted pressure of the slab on the ground is calculated. This data makes it possible to verify the sizing of the foundations by ensuring that the bearing capacity of the soil is not exceeded.

The function in the GSE Concrete software automatically calculates the nodal tributary areas to save users’ time. The foundation can be supported by either: ground springs, regular springs, fixed supports, piles or imposed displacements allowing flexible modeling for the user.

The SAFI GSE Concrete software supports several concrete design standards. With the automated slab generation and design tools in SAFI, the longitudinal reinforcement required to withstand bending forces is calculated according to the design parameters defined by the user. The 3D visualization of the reinforcement is available in the SAFI GSE Concrete software.
Concrete buildings are widely used in the construction industry. In such structures, slabs are key structural elements resisting the gravity and live loads of each floor. The design of concrete slabs is an iterative process. Mainly two aspects must be verified i) the resistance and ii) the deflections of the slabs. Even though the amount of reinforcements are chosen to resist the structural loads, a particular attention must be provided to the deflections of the slabs. Such deflections verification may indicate a need of additional reinforcements of the slabs.
Hence, the cracked deflections of concrete slabs has been developed. The cracking phenomenon increases the overall deflections of the slab. The service limit states ensure that the slab deflections do not exceed the given limit values to avoid causing serviceability problems.

The deflections of concrete slabs are composed of: immediate deflections and time-dependent deflections. The immediate deflections are calculated for the selected load combinations. The shrinkage and creep phenomenon are time-dependent effects causing deflections over long periods of time. The overall deflections of the building is a combination of both the immediate and time-dependent deflections.

The immediate cracked deflection calculations require an iterative analysis procedure where the loads are applied progressively. The initial finite element stiffness is calculated using the concrete isotropic elastic properties. As the loading intensity increases, the flexural efforts in the slabs also increase.
The reinforced concrete slab design assistant allows the user to quickly generate the design strips of a concrete slab. The assistant generates column strips and middle strips that are adapted to the geometries of the bidirectional span of the slab. This assistant is directly linked to the automated mesh generation functionalities, allowing us to use the geometrical elements such as supports, walls and openings for both the finite elements model and the design strips generation.
Concrete Slab and foundation design
The CONCRETE CALCULATOR™ is a complementary application of the GSE CONCRETE program. This application is made to provide quick answers to common problems without the overhead of a full structural design program. It is a very handy and productive tool associated with the GSE CONCRETE program. Large number of solved problems and references are available.
The CONCRETE CALCULATOR™ is a simple and powerful tool which allows to analyze and design reinforced concrete beams, slabs and columns cross sections. Analysis and design of a single concrete sections or multiple sections. The program supports the American ACI-318-02 code, the Canadian CSA-A23.3-04 code, the Egyptian design code ECCS 203-2001.
The FOUNDATION CALCULATOR is a complementary application of the GSE CONCRETE program.

The FOUNDATION CALCULATOR allows the user to quickly and easily design reinforced concrete footings without the need to create and analyze a complete structural model (nodes, members, load combinations, etc.).

This Engineering Calculator supports the American ACI-318-02 code, the Canadian CAN/CSA-A23.3-01 code, the Egyptian code ECCS 203-2001.

The FOUNDATION CALCULATOR allows to perform the design of four different types of footings. Each type of footing can be designed with a certain type of column.
-Isolated square footing: reinforced concrete column or steel column
-Isolated rectangular footing: reinforced concrete column or steel column
-Strip footing: reinforced concrete wall
-Combined footing: reinforced concrete column or steel column
