Week 12 Challenge

Aim:- To calculate the Barge Impact load of the Panamax vessel on the bridge shown in figure.

Explaination:- In this analysis of impact load generated by brage observed, this is in recenet one of the most imoportant in new topic where researcher are also trying to find out which size, dimension of the pier will be most sutaible for the given impact and waht will be the maximium permissible limits the section can resist the impact. In the analysis we tried to calculate the actulate impact load generated by the barge and analysied the results.

Caculation:-

Brage impact load calculation,

Dead weight:- 52500 DWT

No.s of container:- 4500

Each container is standard:- 6.1 TEU

Speed = 60 km/hr =16.67 m/s

Length= 294m,

KE= 500*Ch*W*V^2

KE= 500*1.25*52500*16.67*16.67= 9.2*10^9 N-m

Brage Depth:-

aB= 3100{((1+1.3*10^-7*KE)^0.5)-1}= 3100{((1+1.3*10^-7*9.2*10^9)^0.5)-1}= 103676 mm

aB > 100 mm, so

Pb = 6*10^6+1600(103676)= 1.67*10^5 kN

Staad Pro modelling:-
