C Battens shall be designed to resist simultaneously the following.

. 3 implies single lacing with welded connection. They are designed as short columns. 5 implies batten with riveted connection.

Single and double lacings are the most common out of these types. The chords battens and joints of battened compression members should be checked under the design forces and moments at mid-length and in an end panel. Types of Lacing There are five general types of lacing namely single lacing double lacing battens lacing and battens and perforated cover plates to be used under different field conditions.

Longitudinal shear V Vt CNS and Moment M Vt C2N where Vt is the transverse shear force C is the distance between centre-to-centre of battens longitudinally N is the number of parallel planes of battens and S is the minimum transverse distance between the centroids of the boltrivet groupwelding. If the same section mentioned above is subjected to moment acting about Z-Z axis which is very rare in practice the moment will be shared by the 2 nos. The following table gives the parameters that are required for Lacing or batten design.

The course also comprises of analysis and design procedure of steel members under axial tension. The shapes of these five types are shown in Figure 325 whereas single and double lacing are compared in. Built-up CFS column with lacings and battens.

2007 the battens shall be designed to carry the Bending moments and shear forces arising from transverse shear force V equal to 25 of the total axial force on the whole compression member. It consists from four parallel chords with cold-formed C cross-sections which are interconnected by lacing in one plane and by battens in four perpendicular. Battens is to check buckling of components in case of i and transfer of lateral forces in case iii.

The basic steps in designing column splices are. In the case of ii the one component will be under compression other one under tensionand lacing must resist the buckling of compression component There has to be an additional 25 transverse shear ie. 1is the number of lacing planes and d is the length of the diagonal.

The total design value of the horizontal force. 2 implies double lacing with riveted connection. Design the end connections for the batten system to resist calculated longitudinal shear and moment Design of Column Splices Splices are used in joining members whose length is less than the required length.

25 of Mdfor batten design. 6 implies batten with welded connection. Lacing Batten Double channel sections back-to-back and face-to-face can be joined either by lacing or by batten plates having riveted or welded connection.

Determine the load for the design of the splice. It deals with the design procedures of flexural members having laterally supported and laterally unsupported beams. Lacing are provided in diagonal while battens are provided in horizontal direction.

1 implies single lacing with riveted connection. The course also comprises of analysis and design procedure of steel members under axial tension. Which of the following forces is used for the design of batten of a built column.

The course also comprises of analysis and design procedure of steel members under axial tension. As per clause 77. Design of compression members built-up compression members along with the batten and lacing systems are explained in in this course.

Various recommendations on design details for battened members are provided in clause 6432. It deals with the design procedures of flexural members having laterally supported and laterally unsupported beams. Design of compression members built-up compression members along with the batten and lacing systems are explained in in this course.

The rules governing design of lacings and battens as specified in clauses 7677 and 78 of IS 800. So batten plates unlike lacing lacing platesare placed in inclined way where the batten plates are placed perpendicular to the axis of thecolumn that means if columns are vertical then batten plates should be horizontally placedNow batten plates are generally placed in both the side with equal spacing and in both theside at same position we provide batten plates and minimum. Design of compression members built-up compression members along with the batten and lacing systems are explained in in this course.

It deals with the design procedures of flexural members having laterally supported and laterally unsupported beams. 2007 are to be strictly adhered to. And battens fails first because of less effective area way they are provided than the lacing.
