Guest Editor's Note This volume presents a special issue on "Structural Assessment and Health Monitoring" and is composed of ten papers. Both experimental and analytical studies on structural behaviors are presented in this issue: Professor Jiang investigates the effects of the vertical setback of high-rise buildings on earthquake responses and checks the rationality of the provisions for the structures with vertical setback specified in the current design codes from their extensive analytical works. Professor Sanada proposes an equivalent linearization method which can be applied to high-rise buildings equal to or shorter than 60 m in height, which do not require earthquake response analysis in the Japanese seismic design code. Professor Kim describes the full-scale experimental works of which aim to evaluate the interfacial stress concentrations on the connection between vertical through-plate and H-beam in CFT column. Dr. Qi introduces a new method based on the visual characteristic of the objects and machine-learning technology to achieve semi-automated recognition of the personnel, machines & materials of the construction sites. Professor Mastumoto clarifies the long-term mechanical performance of a steel truss member strengthened by a carbon fiber-reinforced polymer without a protective coating through exposure test, and proposes a calculation method of bending stiffness. Professor Kim proposes a model (Transfer Learning enabled EfficientNet, TL-EN) for automatic detection of cracks on high rise building surfaces from the live stream video captured by an unmanned aerial system. Professor He examines the possibility of the structural condition assessment by using the proposed steel slit shear wall (SSSW) through both numerical and experimental research and concludes that the provided equation can be used to design the dimensions of SSSW. Dr. Kashiwa conducts analytical studies on the RC building supported by piles subjected to earthquake loadings, in order to evaluate the effect of nonlinear soil-structure interaction on the superstructure and pile foundation. Ms. Choi introduces the Ministry of Taxation (MOT) tower which has a unique and futuristic shape and became a new national landmark of Azerbaijan. Performance-based seismic design and construction sequence which allow it to be fully realized is also presented. Professor Moon investigates the potentials of conjoined towers as a viable direction for future tall building developments creating more sustainable vertical built environments. In the end, the editors would like to appreciate all the authors for their paper submission and their distinctive, valuable research works. We also would like to greatly appreciate the support of IJHRB Chief Editor Professor Emeritus Kim Sangdae and his staff .
