Abstract

The present study investigates the influence of the number, material and Configuration of Bolts on Rigid Bolted Connections under Fire. In this study, 6 steel Rigid Bolted Connection specimens with end-plate were modeled as A490 and A300 in ABAQUS software and they are assessed under Fire by nonlinear dynamic analysis. By examining the results, the highest stress in the bolt is occurred with material A300. This is due to the lower yield stress of the A300 bolts than to the A490 because the A300 bolts yield at lower stresses and, as they enter the plastic deformations, cause the steel plates to become more involved and the values Increase the stress, especially around the bolt holes. Sample stresses CON. M22 8B A490 and CON. M18 12B A490 T2 are different about 4%. This displacement value for specimens with A300 Bolt Materials increases to 240 MPa which is equivalent to the yield stress of material A300. The strain with material A490 for CON. M22 8B A490 and CON. M18 12B A490 T2 samples is about 59% and for CON. M18 12B A490 and CON. M22 8B A490 T2 samples is about 67%. The strain with materials A490 for CON. M22 8B A490 and CON. M18 12B A490 T2 samples is about 38% and for CON. M22 8B A490 and CON. M18 12B A490 samples is about 20%. Specimen displacement for bolts with materials A490 whereas this value for specimens with A300 bolts for CON. M22 8B A300 and CON. M18 12B A300 T2 specimens had the highest and lowest vertical displacements, respectively, which is about 25% difference. In the CON. M22 8B, CON. M18 12B and CON. M18 12B T2 samples with different Bolt Materials, the percentages are 15, 24 and 44%, respectively. The use of materials with lower yield and rupture stresses caused yielding in the lower temperature and reducing the resilience of structure under Fire.
