What is the output produced by this analysis?
Sure, you can copy and paste the script to get the answer. But that’s no fun.
Think about the model and analysis. Can you explain what’s going on before getting the answer?
import openseespy.opensees as ops
ops.wipe()
ops.model('basic','-ndm',1,'-ndf',1)
N = 365
ops.uniaxialMaterial('Elastic',0,1.0)
for i in range(N):
ops.uniaxialMaterial('Multiplier',i+1,i,1.01)
ops.node(1,0); ops.fix(1,1)
ops.node(2,0)
ops.element('zeroLength',1,1,2,'-mat',N,'-dir',1)
ops.timeSeries('Constant',1)
ops.pattern('Plain',1,1)
ops.sp(2,1,1.0)
ops.constraints('Transformation')
ops.system('UmfPack')
ops.analysis('Static','-noWarnings')
ops.analyze(1)
ops.reactions()
print(-ops.nodeReaction(1,1))
