Effect of Corrosion Time on Critical Buckling Load of AISI 304 Columns


In this work Corrosion buckling interaction behavior of AISI 304 stainless steel circular columns was investigated. Long and intermediate columns diameter of (6 mm) are tested in as received and corroded condition. Corroded columns are tested after embedded it in soil for different times. Rotating buckling machine test was used to evaluate the critical buckling load (pcr) under dynamic compression loads. By using Perry Robertson formula, experimental work results are compared. The results showed that increasing in corrosion time (embedding time), the reduction in critical buckling load increases also. Maximum reduction of buckling load value are (2.28%, 1.37%) for long and intermediate column respectively as compared with as received condition.
