The work is illustrated for beam as well as plate problems. Excellent agreement is obtained for shape-sensitivity calculations that compare exact solutions, fixed-basis finite-element results, and overall finite-difference approximations to the finite-element sensitivity results. It is illustrated that ...
Natural frequencyMechanical vibrationLinearizationThe dynamic characteristics of structures (beams and plates) can be significantly changed by embossing small out-of-plane patterns in these structures. Recent results in literature show, both numerically and experimentally, that shaping a beam in the ...

AbstractKinked rebar is a special type of steel material, which is installed in beam column nodes and frame beams. It effectively enhances the blast resilience, seismic collapse resistance, and progressive collapse resistance of reinforced concrete (RC) structures without imposing substantial cost burdens...
