Torque for HT / HSFG Bolts

Dear Readers,Wish You a Happy Durga Pooja.

 

Based on my previous posts you may familiar with grades of bolt, torque of bolt, torque calculations and slip factors. However it is a real challenge in construction industry to determine the torque for bolts. Technically it is based on the applications. Some times client mentioned in drawings or you may get it from technical specifications but most of the times both are missed out. Given below is an ideal chart. This is one of my rare collections. Hope it will be very useful to all engineers.

Properties of ISJB

Dear Readers,

This is continuation with my earlier post "Unit Weight of ISJB", self would like to post the sectional properties of ISJB. This will be good alternate for ISMB and ISLB.

Properties of beams are having two parts. One part is Physical dimensions and another part is sectional properties of ISJB. Basically dimensional part contains depth and width of section, Thickness of Web and Flange and Root Radius. Where as sectional properties contains Moment of Inertia, Radius of Gyration and Section Modulus. These are useful for design engineers.

Unit Weight of ISMCP

Dear Readers,

Wish You a Happy Engineer Day-2012

In continuation with my earlier post of ISMC, Let us discuss about ISMCP (Indian Standard Medium Weight parallel Flanged Channel)

This is one of the standardized categories of hot-rolled steel Channel section. This is same as medium weight channel, all dimensions are same as medium weight channel However radius of channel flange is varying . It is parallel flange rather than a tapered flange.

It is also identified as a PFC (Parallel Flange Channel). It is designated as web size and flange size with prefix of MCP and having sizes from 75mm to 400mm. Example is MCP 300 X 84, where 300 is web size and 84 is flange size.
