VECTOR ALGORITHM FOR LAYERED REINFORCED-CONCRETE SHELL ELEMENT STIFFNESS MATRIX
MIN CS, GUPTA AK
Abstract
A new vector algorithm is presented for computing the stiffness matrices of layered reinforced concrete shell elements. Each element stiffness matrix is represented in terms of three vector arrays of lengths 78, 96 and 36, respectively. One element stiffness matrix is calculated at a time without interruption in the vector calculations for the uncracked or cracked elements. It is shown that the present algorithm is 1.1 to 7.3 times more efficient then a previous algorithm developed by us on a Gray Y-MP supercomputer.
