Vector algorithm for reinforced concrete shell element stiffness matrix
Chang Shik Min and Ajaya Kumar Gupta

 
Abstract
    A vector algorithm for calculating the stiffness matrices of reinforced concrete shell elements is presented. The algorithm is based on establishing vector lengths equal to the number of elements. The computational efficiency of the proposed algorithm is assessed on a Cray Y-MP supercomputer. It is shown that the vector algorithm achieves scalar-to-vector speedup of 1.7 to 7.6 on three moderate sized inelastic problems.
 
Key Words
