Guidelines for Numerical Analysis and Seismic Design of Modeled Underground Structures

This book provides a comprehensive study of the dynamic behavior of buried structures subjected to seismic actions caused by accidental explosions. It presents parametric analyses of the effects of various explosion scenarios on steel and concrete pipes, exploring energy generation, stress components, and time history based on varying pipe thicknesses and burial depths. The study also examines the influence of different soil types and friction coefficients on buried pipes, offering valuable insights for practicing engineers. Additionally, the book includes findings on groundwater quality assessments from sedimentary formations and basement complexes, as well as the pressure load variation and expansion characteristics of palm kernel shell-stabilized sedimentary formations in South-Western Nigeria. The results of these studies serve as practical guidelines for seismic design and numerical analysis of underground structures.

This book presents the results of a detailed study on the seismic behavior of buried structures, focusing on the impact of accidental explosions. It covers parametric analyses of energy generation, stress variation, and time history in steel and concrete pipes subjected to internal and surface explosions in different ground media. The book also discusses the effects of friction coefficients and embedment ratios on buried pipes. In addition, it explores the quality of groundwater from sedimentary and basement formations, as well as the pressure load and expansion characteristics of palm kernel shell-stabilized sedimentary formations in South-Western Nigeria. These findings provide critical guidelines for engineers involved in the seismic design and analysis of underground infrastructure.
