Structural safety upgrade has become an urgent global need due to both widespread construction obsolescence and more stringent construction code requirements, especially in earthquake-prone areas. Increasing economic resources are employed for structural rehabilitation of existing structures, urging reaserchers in the academic world towards the development and investigation of advanced retrofitting and strengthening techniques that are efficient and affordable. The objective of this Special Issue is to collect innovative research studies on advanced methods for structural rehabilitation of buildings. Innovative experimental, analytical, and numerical studies, new design methods and case studies, applications to real cases, state-of-the-art reports, and other original research findings are invited. For this Special Issue, we are particularly interested in inviting papers focusing on: (i) strengthening with FRP-based techinques of RC members, (ii) strengthening with FRM, TRM and FRCM of masonry walls, (iii) new strengthening materials and techniques, (iv) seismic protection devices, (v) protection of non-structural elements, (vi) cost-benefit analysis, (vii) conceptual design, and (viii) new developments in code making.
