The nonlinear analysis is replaced by sequentially linear analyses (SLA), and a smeared, fixed concrete cracking model was used. A notched concrete beam was employed for validation. Using a crack band width factor of 2.0 and 10-mm nodal spacing, the peak load differed by only 3.5% from experimental results. Overall results were similar to experimental ones, as well as to those published by researchers using finite-element SLA. The approach provides two major advantages over finite-element-based SLA: (1) nodal distortion insensitivity, and (2) nodal spacing insensitivity.||Funding Details:||European Research Council||Type of material:||Journal Article||Publisher:||American Society of Engineers||Copyright (published version):||2015 American Society of Civil Engineers||Keywords:||Mesh free method;Point interpolation method;Sequentially linear analysis;Concrete;Cracking||DOI:||10.1061/(ASCE)CP.1943-5487.0000474||Language:||en||Status of Item:||Peer reviewed|
