Underground structures must be able to support static overburden loads, as well as to accommodate additional deformations imposed by seismic motions. It seems well established that the most critical demand to the structure is caused by shear waves traveling perpendicular to the tunnel axis, which cause distortions of the cross section (ovaling for a circular tunnel, and racking for a rectangular tunnel) that result in axial forces (thrusts) and bending moments. While all this has been well-studied for structures placed in linear-elastic ground under drained loading conditions, there is little ...

This book will provide comprehensive, practical knowledge for the design of reinforced concrete buildings. The approach will be unique as it will focus primarily on the design of various structures and structural elements as done in design offices with an emphasis on compliance with the relevant codes. It will give an overview of the integrated design of buildings and explain the design of various elements such as slabs, beams, columns, walls, and footings. It will be written in easy-to-use format and refer to all the latest relevant American codes of practice (IBC and ASCE) at every stage....

Historia del cartucho 9 Parabellum, su eficacia, el por qué de su nombre, todo lo que rodea a este famoso cartucho claramente explicado. Descripción de los principales tipos de proyectil empleados, así como de los materiales de la vaina. Cartuchos derivados de él y otros con las mismas medidas

Actualmente la fabricación de estructuras de hormigón supera a la del resto de materiales de construcción considerados conjuntamente. Este hecho unido a la importancia técnica, económica y social del sector de la construcción explica que el deterioro de las estructuras de hormigón armado se haya constituido en el reto principal de la ingeniería civil en el mundo desarrollado. Los autores de este libro, basándose en su experiencia de más de tres decenios, pretenden despertar en los estudiantes, técnicos e investigadores la inquietud por el análisis de las causas que provocan la...
