Unexpected catastrophic events often lead to upgrading established provisions. Since the 1960s when extensive research commenced to embrace earthquake-related subjects, dramatic improvements have been made in terms of modeling and design approaches. The functionality of constructed facilities under seismic loading needs to be maintained within a tolerable range of damage or their constituents may fail in a ductile manner attempting to ensure user safety. For substantiating the performance of proposed methodologies, laboratory tests are conducted in conjunction with finite element analysis, which form the technical foundation of site implementations. The third part handles case studies emphasizing an upgrade of school buildings that are non-conforming to contemporary specifications and guidelines. The second part discusses retrofit procedures alongside specific provisions dominating the requirements and techniques appertaining to ground motions.

These documents are mandatory for the legal adoption of a model code by the governing jurisdiction where the building in question is to be located. The first part of the review examines design standards and guidelines that are used in the structural engineering community. Background information on the behavior of existing buildings subjected to earthquake loadings is gathered and rehabilitation methodologies are elaborated. The resulting debris and impacts with structural elements are also automatically analyzed and stress redistribution is inherently calculated.This paper presents a synthesis of current practices in regard to the seismic analysis, design, and retrofit of built-environments. This allows ELS is to automatically analyze structural behavior during elastic and inelastic modes including the automatic yielding of reinforcement, detection, and generation of plastic hinges, buckling & post-buckling, crack propagation, membrane action & P-Delta effect, and separation of elements. Unlike many structural analysis software tools which are based on the Finite Element Method (FEM), ELS utilizes a non-linear solver based on the Applied Element Method (AEM).

This includes static and dynamic loads such as those generated by a blast, seismic events, impact, progressive collapse, and the wind. ELS allows structural engineers to study the 3D behavior of structures through both the continuum and discrete stages of loading. Extreme Loading ® for Structures Software or ELS, is an advanced non-linear structural analysis software tool designed specifically for structural engineers.
