General tab

Bolts tab

Use the Bolts tab to control the bolt properties. If anchors are used instead of bolts, the fields for bolt rows, spacing and edge distance remain active.

Option Description
Bolt size Bolt diameter. The default value is 16 mm.
Standard Bolt assembly standard/grade. The default value is 4014-8.8.
Tolerance Tolerance = Hole diameter - Bolt diameter. The default value is 4 mm.
Thread in material Indicate if the thread of the bolt can be inside the bolted parts. Tekla Structures does not use this value when calculating the length of full-threaded bolts.
Bolt type Define whether the bolts are assembled on-site or in the shop. The default value is On-site.
Bolt rotation options
 
Option to set the bolt group rotation. This option is available when on the Anchors tab the option Base plate with is set to Bolts or Bolts and custom part
Standard
Bolt direction 1
AutoDefaults can change this option.
Bolt direction 1
Bolt direction 2
Slotted hole X and Y Slotted hole dimensions can be set in x- and y-direction. These fields can also be used to set the tolerance of oversized and tapped holes.

Standard 0 mm is set, which results in a round hole.

Hole type Default, oversized, slotted, or no holes. Slotted creates slotted holes. Oversized creates oversized holes or tapped holes. No holes creates no holes, which can be used for plates which are screwed.
Rotate Slots Default odd, even, parallel. If the hole type is set to slotted, this option can be used to set the rotation of the slotted holes:
Cut length Indicate which parts the bolt connects. The value defines the area Tekla Structures should search for parts that belong to the bolt group. Using cut length you can determine whether the bolt will go through one flange or two.
Bolt Comment Bolt comment.

If you want to create only holes without any bolts, clear all the check boxes.

The option Effect in modify enables the bolt assembly to be modified in existing components when the existing component is modified. 
Extra length Additional bolt length. Increases the material thickness that Tekla Structures uses when calculating bolt length. For example, you might need extra bolt length to allow for painting. You can also build additional lengths into bolt assemblies.

Use the Extra plate to add extra vertical plates which for example can be used  to mount wallplate that represents a structure such as a wall or roof panel

In Tekla Structures, a panel is created by picking two or more points.

In cast-in-place concrete the term wall refers to a concept similar to panel.

panels.

Fields a up to f can be used, depending on the selected option. 


 

2 Overlap/offset of the extra plate from the base plate top.

Concrete tab

Use the Concrete tab to define recesses in case the base plate is created for a concrete column. The recesses can be used to create clearanceset space between objects

In bolted connections, clearance is required for entering and tightening the bolts with an impact wrench. In addition to this, there may be a clearance for a fillet.

In welded connections, clearances are required in order to allow a welder to lay a correct weld.

Reinforcing bar clearance defines the minimum clearance or the allowed overlap for reinforcing bars when they are checked against other objects.
