Lecture 38 : Connection Design of Lacing Systems

[@hasanshirazi9535]

@23:29 If we have to provide 2 bolts, how can they be arranged within the overlapped portion of strips while maintaining p and e distances?

[@gautamraj-f7d]

We do not prefer to increase the number of bolts in lacing, but we will increase the diameter of the bolt if necessary.

[@anetalkar6993]

In case of bolted connection length of tie plate considered is s+2b whereas in welded connection length of tie plate considered is s+2g why the difference?

[@vaibhavmishra3269]

@23:28 bolt value should be 74.294

[@ashimvlogs2927]

Yup

[@ashimvlogs2927]

No worrie..result are same though..1 bolts

[@gautamraj-f7d]

Yes... sir remembered the single shear value.. it should be 74.294

[@hasanshirazi9535]

@15:32 If there is only one bolt then what is the significance of pitch p?

[@sbchannel2268]

i am thinking also sir ...i am very poor bitech student ... total confused sometime in lecture ....

[@Sanskarshalakids]

To calculate the number of bolts required we need strength of bolt in bearing for that we have to calculate Kb, and for calculating kb we have to calculate pitch p. As in earlier stage we don't know how many bolt will be required. As the strength of bolt will be the least of strength in shearing and bearing.
