C- Static analysis and design of bar elements

While the structural analysis of the steel structure is carried out, the main structural system and secondary structural elements are involved. Secondary structural elements such as roof, wall, wind column, intermediate secondary beam, crane walkway transfer the loads they receive from the pavements they are related to to the main carrier system. For this reason, the design of the secondary structural elements are made priorities and then the analysis and design of the main carrier system is carried out.

Eurocode-3, CYTHYE-2016, AISC-360-10 and AISC-360-16 standards can be used for the design of steel structure elements in MkaPEB. Since there is no detailed calculation method for the light steel construction elements preferred for use in roof and wall purlins within the new steel structures regulation, these elements are designed according to Eurocode-3-1-3 at MkaPEB.

C-1.1 Design of secondary structural elements - ROOF PURLINS

As we have shown in the load analysis section, there are regional differences when wind and snow loads (due to snow accumulations) transfer loads to the roof planes. Therefore, each roof plane is considered separately. The analysis page has two separate controls, up and down. In the downward control, the dominant load is snow, while the upward direction is wind. These analyzes were carried out considering that there may be regions with low snow loads and high wind loads.

C-1.2 Design of secondary structural elements - SIDE and SHIELD WALL PURLINS

They are the structural elements that transfer the loads coming from the coating on the side walls to the main carrier system. Wind, coating core, purlin is calculated by taking into account their own loads. The critical question here is the wind load. Wind loads from left, right, front and rear affect this structure. As you can see in the section on load analysis, these loads vary according to the geometry of the structure and the wind direction. MkaPEB checks each purlin separately according to the load combinations created for all wind loads.

C-1.3 Design of secondary structural elements - GANTRY CRANE WALKING PATHS

C-2.1 Design of main structural elements - YZ AXLES (Vertical direction to steel scissors)

In the direction perpendicular to the steel shear, the steel columns are connected by stability crosses. If the structure is long, it is possible to define a dilatation gap in MkaPEB. Due to seasonal temperature changes, the structure is shortened and elongated. In Turkish regulations, there is no clear statement about how many meters a thermal dilatation gap will be left in steel structures. In an article about Eurocode-3, it is stated that if the length of the building exceeds 60 meters, either a thermal dilatation gap will be made or the effects arising from the temperature difference will be taken into consideration in the analysis. At MkaPEB, temperature differences are taken into account in all circumstances.

Particularly in central crossed systems, because of the high rod length, the slender conditions cannot be exceeded in the pressure-operated rods. While analyzing the YZ axes, the pressure from the central diagonals was removed from the system as if they were never used.

The static analysis of the YZ axes and the design of the stability beam and cross members connecting the columns are not only related to the tensile force in steel structure regulations but also to the conformity of the slenderness and cross-sectional dimensions in the earthquake regulations. In the YZ axles, a plurality of cross members are connected to the column. MkaPEB calculates these combinations according to the user's choice of welded or bolted connections. It automatically applies the longest welding length or maximum bolt diameter / piece information to all crosses in the most negative situation when all crosses are combined.

C-2.2 Design of main structural elements - XZ AXLES (Steel shear line)

Loads from the secondary structural elements shall be carried by the main carrier systems. This load transfer is done by MkaPEB. XZ axes are grouped by comparing the number of bars, number of joints, overhead crane and spacing, and static analysis is performed for the axles with the most negative loads. In the design of the bars and joint joints, the required load combinations are automatically generated by considering the loads acting on the structure as specified in the selected standards. Before the static analysis of the XZ axes, the effective period of the structure is calculated in accordance with the selected earthquake regulations. The earthquake regulations that can be selected are TDY-2018, ASCE-341-16, Eurocode-8, EAK-2000 (Greece). After the static analysis, the conditions of the selected steel structures, as well as the conditions specified in the earthquake regulations, the delicate conditions specified by the earthquake regulations, the relative displacement of the floor, the limitation of the effects of the second order, the conformity of the dimensions of the rod element sections are checked.

E- Detailed account report preparation

Today, the most common method of accounting report preparation is to give the results in tables. Since the civil engineer who prepared the project in such reports cannot control the accounts step by step, the program has no choice but to trust the producers. If there is a faulty transaction and/or calculation, it must be determined and corrected by someone else.

MkaPEB prepares detailed reports that show you step by step how snow, wind and earthquake loads are obtained, how the bar elements and joint calculations are made.

Sample account reports

• Load analysis
• Design of a steel column

Within MkaPEB, there are many regulations regarding the loads that affect a large number of structures, the earthquake regulations and the accounting rules for steel structures. Our goal here is that you can make projects abroad before MkaPEB is used abroad. Our program can also prepare English versions of detailed account reports that you can see above.
