Book Description
The purpose of this book is to expand the knowledge and skills of civil and structural engineers and researchers and help them better understand, design, and analyze civil engineering applications. This book examines advancements in structural integrity and failure and underground construction. It offers profound insights into the mechanisms that can lead to the integrity or failure of structures and result in safe underground construction. It provides details on the fundamental principles, theories, behavior, and performance of different structural elements and underground construction. The book delves into the mechanics, design, and construction of reinforced concrete structures. It explores the design principles applied to reinforced concrete structures and considers critical structural elements like beams, slabs, columns, and foundations. It also demonstrates various advances in reinforced concrete technology, including high-performance concrete, fiber-reinforced concrete, self-compacting concrete, and the use of nanomaterials. It describes methods for the analysis and evaluation of reinforced concrete structures, non-destructive testing methods, structural health monitoring, finite element analysis, and causes of failure. In addition, the book proposes a design model for determining the flexural bearing capacity of reinforced concrete beams having reinforcement steel with reduced modulus of elasticity. Moreover, the book investigates the effects of loading rates on the mechanical properties of structural steel. It also evaluates the formation of welding defects in the process of connecting steel structures, which is inevitable, from the aspect of failure mechanics. In addition, it utilizes an equivalent shell-wire model to propose a simple accurate technique for nonlinear assessment of reinforced concrete shear walls with less computational cost. The book introduces tunnel design theory and method, support structure systems, construction technology, and equipment under complex geological conditions. Furthermore, it highlights procedures to design efficient dewatering systems considering the working conditions, stability, and impacts generated in the vicinity of construction, and to examine the state of retaining walls by using hydrogeological tools. Finally, it outlines the online monitoring and intelligent diagnosis mechanism of key equipment in the subway ventilation system.

Book Description
This Research Topic is Volume II of a series. The previous volume can be found here: Coal and Rock Dynamic Disasters: Advances of Physical and Numerical Simulation in Monitoring, Early Warning, and Prevention With the soaring growth of global population and socioeconomy, energy consumption and demand has been rapidly rising, and coal would still remain a fundamental energy source for a long time into the future. Seeking deep coal resources becomes an inevitable trend due to the depletion of shallow coal resources. Deep mining of coal resources promotes socioeconomic development, whereas bringing a variety of security challenges. In deep underground, there is a significant risk increase in coal and rock dynamic disasters (CRDDs), owing to the changes in physical and mechanical properties of coal and rock. In this regard, it is of great importance and necessity to prevent and control CRDDs effectively and efficiently.
