I want to perform impact analysis of an aircraft to building. How to generate time history of applied impact force. Is there any method available to generate time history for impact force to be input in software. The mass of aircraft is 1000 tons velocity 5m/s and assumed distance before...

Span 10m, Outer Dia 500mm, Thickness 5mm Hinge support on both ends

I have performed collapse analysis for a simply supported tubular beam by applying load at centre. And I am getting load Vs deflection curve at mid point as per attachment. Can anyone explain what is the reason for this type of...

I am performing pushover analysis by incrementing load upto impacted member failure and getting the total energy absorption. What I understood is that I have to design the structure for only one lateral load i.e. ship impact load. Other loads will be taken care off as ship impact will be...

In design of Offshore jacket platform, I am having wave & current loads and ship impact load as lateral loads. Fr analysis purpose there are two types one is linear static analysis without effect of ship impact and another is ship impact analysis (nonlinear static pushover) without wave loads...

For collapse analysis in SACS the collapse input (clpinp) requires number of increments, start and end load factor for applied point load. How to set these values such that structure will collpase? I want to find energy absorption at collapse of Structure.

I have a beam fixed at both ends with tubular cross section, length 10m, yield strength 250Mpa, Dia 250mm, Wall thickness 5mm. I want to find the value of point load at centre for is elastic limit. Elastic Deflection will be Wl3/192EI and strain limit is 0.2% but how to find the maximum load at...

After performing dynamic ship impact analysis in SACS, in chartvue it shows energy absorption curves for ship and structure. On what theoretical basis SACS considers energy absorption by ship? Can anyone explain about interpretation of chartvue results in SACS i.e. Energy, Joint displacement...
