Buntara S. Gan – författare

This book proposes a novel, original condensation method to beam formulation based on the isogeometric approach to reducing the degrees of freedom to conventional two-node beam elements. In this volume, the author defines the Buntara Condensation Formulation: a unique formulation in condensing the dynamic equilibrium equation for beam structures, suitable for reducing the number of unlimited dynamic equations necessary to yield a classic two-node beam element. Professor Buntara’s method overcomes the problem of the isogeometric approach where the number of degrees of freedom is increased along with the complexity of the geometrical beam element and facilitates implementation of the codes into the existing beam structures programs, and CAD geometrical data into the conventional FE beam element codes. The book proposes a new reduction method where the beam element can be treated as under the conventional beam element theory that has only two nodes at both ends.

This book is a collection of papers presented at the 5th International Conference on Rehabilitation and Maintenance in Civil Engineering (ICRMCE 2021), held in Surakarta, Indonesia. The papers are grouped into sequential themes representing the structure of this book:

o   Part 1: Factors affecting building and infrastructure performance

o   Part 2: Testing and inspection of existing building and infrastructure

o   Part 3: Protection, maintenance, repair, and retrofitting of building and infrastructure

o   Part 4: Maintenance management of building and infrastructure

o   Part 5: Service life modelling of building and infrastructure

o   Part 6: Hazard mitigation

o   Part 7: Sustainability aspect in civil engineering design, process, modelling, maintenance, and rehabilitation
