The interest in software which examine the behaviors of the buildings according to loads affecting by simulating buildings by construction engineers and which design them has increased fairly in the recent years.

1- Modeling with Parametric Information Input

  • 1-1. Joining trusses, changing their sizes.
  • 1-2. Changing distances between trusses, determination of locations of roof and side diagonals, determination of location of thermal expansion (dilatation) gap
  • 1-3. Determination of locations of mezzanines and cranes, determination of locations of mezzanine truss type and columns bearing the mezzanine.
  • 1-4. Determination of types of wall braces.
  • 1-5. Fixed, movable, built-in support or columns can be defined to nodal points of the roof system. Column bottom level can be changed.
  • 1-6. Determination of Wind columns' location.

  • 1-7. In case where there are more than one roof bearing systems, truss may not be on some axes.
  • 2- Collective Cross-section Change

  • 2-1. Changing frame cross sections of roof bearing system.
  • 2-2. Changing column cross sections.
  • 2-3. Changing cross sections of wall stability elements
  • 3- Automatic Load Transfer

  • 3-1. Snow Loads: They are calculated by considering parameters such as whether the structure roof is with one or two flows according to EN-1991-Part 1-3, whether there are places that snow may accumulate and etc. and National Annexes of 16 countries. Firstly, they are transferred to purlins and then from purlins to roof bearing system automatically.
  • 3-2. Wind Loads: They are calculated by considering the category of the land where the building is according to EN-1991-Part 1-4, wind speed and sizes of the building. They are transferred to the roof bearing system, wall beam, and to columns automatically.
  • 3-3. Mezzanine Service and Dead Loads: Service loads are determined by considering building classes given according to EN-1991-Part 1-1. They are transferred to mezzanine floor beam and mezzanine beam automatically.
  • 3-4. Thermal Effects: if the building is longer than 60 meters vertical to steel trusses, there are two choices. Either thermal effects are considered or thermal expansion gap should be made in order for the building to shorten and lengthen. In order to be able to calculate thermal effects, temperature differences for winter and summer according to rules stated in EN1991-Part 1-5 and characteristics of the building are taken into consideration. These temperature differences are used in designing wall braces and beams.
  • 4- Design of Secondary Building Elements

  • 4-1. Roof Purlins: They are calculated according to loads of roof cover and snow accumulated on the roof cover. Roof purlins may be formed from hot rolled or cold formed material with sag bar or without sag bar, continuous or discontinuous. In order to find the most economical cross section, it may be found by the software by sifting through profile tables.
  • 4-2. Wall Purlins: their designs are made according to side coating and wind loads on the side.
  • 4-3. Crane Runway: Loads on crane runways are calculated according to EN-1991-Part 1-3. Static analyses are made by sliding loads from the crane to the wheels. Cross section is controlled according to EN1993-1-1, EN1993-1-5 and EN1993-6.
  • 4-4. Mezzanine Secondary Beams: Design is made according to dead and service loads on mezzanine. Stress and displacements are controlled.
  • 4-5- Wind Columns: They can be defined on the points where there is a purlin on the roof. Columns are designed by considering wind load coming from the direction of side rising. Location of roof braces in the plan is decided by Matmas by considering positions of wind columns.
  • 4-6- Roof Braces: Wind loads coming from wind columns are transferred to diagonal system on the roof. Assuming that frame elements working for pressure were buckled, they are removed from the system. Cross section control is made by considering slenderness of axial powers of tension bars remained.
  • 4-7- Wall Stability Elements: In order to provide the stability of a building against earthquake and wind loads coming vertically to main bearing system in an earthquake zone, stability beam and wall braces are used. During designing, thermal effects are taken into consideration. Joints of these building elements with columns and joints between each other are calculated automatically by the software.
  • 5- Static Analysis

    Information used in the calculation of the loads is entered parametrically by the user. These loads are transferred to related nodal points and frame elements automatically. After then, static analysis of the building is calculated with finite elements method and displacements and frame element internal forces are obtained. SLS (Service Limit State) is formed in order to control displacements of the building according to rules in EC-0 and national annexes of the countries, and ULS (Ultimate Limit State) load joints is formed in order to control the resistance by the software. The results can be examined by using graphic interface.

    6- Capacity Checking of Building Elements

    Frame elements are grouped according to material type used. The resistance of hot rolled steel is controlled according to EN-1993-1-1, welded steel elements according to EN-1993-1-2, cold formed elements according to EN-1993-1-3, concrete columns according to EN-1992-1-1. You can examine details of the calculation made from detailed reports.

    7- Detailing and Designing of Joints

    Nodal point joints of steel trusses show differences according to cross section of the elements used and joint element. Rectangular hallow cross sections are cut angularly. When 2L vertical diagonal a cleat is used. In case where circular hallow cross section is used, dovetail should be opened. Software calculates necessary weld thickness and length in double angle trusses and sizes the cleat. In hallow sections trusses, there are controls which are depended on the type of the joint such as punching which should be done according to EN-1993-1-8 and surface collapse etc. These controls are also made by Matmas. This will have you gain a lot of time. In case when insufficiency is seen, cross sections of trusses are changed.

    Joint types to be used in steel portal frame nodal points are known by the software. Information of joint elements can be changed parametrically. You can examine the sizes and results of resistances controls from the tables. Being able to see detailed drawings and 3D views of joints helps to prevent the faults which could be made in designing.

    8- Cost Analysis

    You can see quantities of a number of materials such as steel, concrete, coating, plate and etc. which are used in the building after static analysis with Matmas in the table in the home page. Control is always next to you…

    Detailed quantities can be calculated from quantity reports and the cost of the building can be calculated with Unit prices of Environment end Urbanization Ministry. You can prepare offers fast by adding your prices and additional costs after transferring cost table to MS Excel.

    9- Erection Drawings

  • 9-1. Section Drawings
  • 9-2. Plan Drawings
  • 10- Shop Drawings with Tekla Structures

    You can get a lot of elements of the shop drawings with Matmas. Some of the software used in the design of steel structural in the world can export Tekla Structures just model of the structure. Matmas is the unique software that transfer building model to Tekla Structures with connection macros, in the world.

    11- Reporting

    The important thing for an engineer, not a rate in the last column of the table, are the steps necessary to be able to check account. Matmas the detailed report prepared in different languages, it gives users a chance to see the accuracy of their calculations.
