What are the criteria for maximum and minimum pitch distance as per IS: 800 – 2007.
[5 marks]What is Limit state? Explain various serviceability limit states considered by IS : 800 – 2007.
[5 marks]Two Rectangular plates 85 mm and 70 mm wide and have 12 mm and 20 mm thickness are connected by lap joint to resist factored tensile load of 70 KN. Design a lap joint using M 16 bolts of grade 4.6 and grade 410 plates.
