Past and current stress conditions of temple G1 in My So'n, Vietnam

The work describes a survey of one of the Hindu temples of the monumental area of My Son in central Vietnam, named G1 by Parmentier at the beginning of the XX century. Also, the paper illustrates the results of numerical analyses of the temple both at its current state and at its presumed original conditions. The temple is in a rather bad state, as most of the vaults were already collapsed at the time of Parmentier’s expedition, and further on destroyed during the Vietnam War. Numerical analyses were carried out to evaluate the presumable stress conditions of the still intact temple and determine whether or not the self-weight alone might be the cause for the partial collapse. Also, the current stress conditions were determined, to avert any further possibility of failure. The numerical models take the layered nature of masonry into account. The masonry leaves were supposed to be either perfectly connected or independent, the last one being the less conservative assumption.
