System developers and designers continually optimize and refine the design of components to achieve a high degree of economy as well as satisfy various architectural trends. Roof is one of the most complex components in typical framed residential structures. Roof structures are mainly formed using roof trusses of various types in cold formed roof structures. Number of superior features are offered by cold formed light gauge steel which makes it an attractive material for truss system. Strength stiffness quality and light weight features of cold formed steel trusses makes them ideal for long spans. Complex roof geometric s can be easily achieved since various sections and sizes are available.
While trusses are structurally relatively simple, because of the complex sections used, numerous combinations of loads which need to be considered and the requirement for different roof trusses with different geometries in a house, it has become a common practice to use software programs like Tekla to analyze and design roof trusses. Roof systems using cold formed high tensile steel can be provided to suit various types of roof construction like hips, gables, dutch gables, mansard, etc. Variety of trusses can be used depending on the shape of the roof. Flexibility of roll forming of sections make to possible to introduce more sophisticated fabrication techniques, trusses with different cross sections.
The permanent forces acting on the structures include the self weight of all structural components of the roof and the weight of all permanent fixtures such as solar panels, water tank, air conditioning plant etc. Concentrated load should be considered at mid span of members and when there is an overhang, a load case should consider the application of the concentrated point load at a distance of 100 mm away from the edge. All roof systems components including the truss, battens, cladding and bracing should be designed to act together to transfer all forces to appropriate supports. The application of wind internal pressure needs to be carefully considered while designing trusses which support ceilings. The internal pressure will act on the ceiling plane if the ceiling is fully sealed.
Tekla like software are becoming widely available for analysis of trusses. Analysis helps to find the axial forces, bending moments, shear forces and deflections for all load components. The typical truss connection are those at the apex and heels. The connection between the top chords of a truss to the roof batterns is critical in maintaining the fully restrained condition for the top chord. Web bracing is one of the bracing items which is specific for trusses. This reduce the specific length of the web members. To transfer the horizontal wind loads top chord bracing are designed perpendicular to the span of trusses to the supports. They are required to provide restraint to the roof battens or purlins that act as lateral buckling restraints to the top chord of the trusses when they are in compression. It was emphasized that if a designer is not using computer program to carry out analysis and design they need to exercise a degree of engineering judgment to reduce the number of combination and checks to be computed.

Structural detailing produces accurate drawing for fabrication and erection of structures. Easy constructability depends on the quality of the design. This ensure easy and efficient fabrication of products. Errors in detailed drawing will affect the success of entire project. It will lead to increase in time for finishing the work and also will increase the total cost. Most of the structures are pre-fabricated and site erected so small errors will affect the total construction procedure. The 3d technology of steel detailing of Tekla helps to generate a strong communication link between client, architect, structural engineers, fabricators and erectors.
The report of the requirements is given by the 3D software like Tekla. It helps to overcome the clashes and schedule the work accordingly. Technology of Tekla reduces the time frame required for quality construction. Tekla training institute in kochi
Steel detailing is a vital communication link. Tekla involves creation of detailed drawing for fabricators and contractors. It also includes plans and estimates as well as other reports and important tasks. The structural safety and stability is decided by the efficient shop drawing and erection drawing. It will decide economy in overall costing. 3D detailing give chance to display various alternatives with exact cost estimates. 2D to 3D transformation gave the confidence to complete projects more accurately and errorlessly. It has reduced 75 percent time frame of completing project by using PEB components and custom components. Tekla reports integrated with ERP systems like BOQ, plate summaries shipping list, CNC files etc. are used by industries. Erection sequence based on site condition are also obtained from the detailed drawing.
Cost of manpower has increased at much faster rate than the cost of material. In steel detailing more than one diameter of bolts are designed and used to avoid and reduce gussets and number of bolts. This itself will help to reduce the construction cost and time of construction. Bending of structural beams are avoided by providing connections on bend plates. The increased cost of oil, gas and manpower has increased the cost of hot bending tremendously. Hot bending of plates are much easier than hot bending of structural sections. In structural steel design lighter sections are adopted by providing more secondary members and also the compressive strength of main members get increased. But also handling more number of members per structure reduces productivity too. It will also increase the cost. While detailing to avoid the delay at the time of construction easy availability and inventory of steel sections need to be considered. The deflection of structure, fabrication, and eccentricity in connection and erection methodology all these things need to be taken care off. This will help in efficient behavior of the structure during construction and execution period.
