Foreword
From our birth and through lifes expectations, we grow and develop into the person we become.
The path we follow through life, with its many turns, mountains to climb and crossroads to choose, eventually leads us to our place today, and our final destination. Professor Mitchell Gohnert, my former student at Brigham Young University, has experienced a lifelong desire to be a structural engineer, with a special interest in the design and application of shell structures. This book is the result of his lifelong quest. Just as we are influenced by the teaching and training of others, we also influence others by the teaching and training we give throughout our lives. Mitch has gained much from the many people he has been involved with, and conversely, he has influenced, assisted and guided many through his mentorship and his expertise in the field of shell structures. Good ideas, called inspiration by some, come to each of us during our life.
When acted upon with persistence and determination, these ideas result in great accomplishments that benefit others.

Abstract
Shells, and in particular domes, have a symbolic meaning in many of the worlds civilizations. Some of the most iconic structures incorporate domes as their architectural center piece. Interestingly, most of these structures are religious gathering places, shrines, or temples and are found in cathedrals, stupas, mausoleums, and mosques.
The symbolism of domes is of ancient origin and is associated with deity and the celestial expanse of the heavens. The home of the ancients appeared to be under a heavenly dome, and the circle of the dome, a never ending line, is a symbol of eternity. This symbolism continues to this day, but has evolved over the centuries to include other closely associated meanings. Alexander the Great, and early Persian rulers, adopted domes in their architecture to symbolize their divine authority and power (Smith, The dome: study in the history of ideas. Princeton University Press, New Jersey, 1950; Hiscock, The symbol at your door. s.l.:SP Birkhauser Verlag Basel, 2010).
This practice has endured to modern times, and domes are seen in some of the most famed architectures, such as the US Capitol Building, the Vatican, and many other religious and governmental buildings around the world. The intent is to portray strength, influence, legitimacy of power, and piety. For these reasons, religious and centers of government will always include domes in their architecture.

Shells, and in particular domes, have a symbolic meaning in many of the worlds civilizations.
Some of the most iconic structures incorporate domes as their architectural center piece. Interestingly, most of these structures are religious gathering places, shrines, or temples and are found in cathedrals, stupas, mausoleums, and mosques. The symbolism of domes is of ancient origin and is associated with deity and the celestial expanse of the heavens. The home of the ancients appeared to be under a heavenly dome, and the circle of the dome, a never ending line, is a symbol of eternity. This symbolism continues to this day, but has evolved over the centuries to include other closely associated meanings.

This practice has endured to modern times, and domes are seen in some of the most famed architectures, such as the US Capitol Building, the Vatican, and many other religious and governmental buildings around the world. The intent is to portray strength, influence, legitimacy of power, and piety. For these reasons, religious and centers of government will always include domes in their architecture.
The endurance of this symbolism is fitting and appropriate, considering the seemingly mystical strength and the eternal nature of these structures. If we go back in history more than a thousand years, remnants of antiquity usually amount to nothing more than a pile of rubble, with the exception of a few columns standing here and there. However, of the structures that have survived, the vast majority are domes and arches.
The Pantheon in Rome (126 AD) (Fig. ) are prime examples. Both of these structures were built in seismic active regions and have been subjected to several major earthquakes; yet they stand today and are in remarkably good condition.
