The evolution of seismic codes and practices in US and Mexico are briefly described and critically analyzed in the following sections. In its technical guidance Repairing and rebuilding houses affected by the Canterbury earthquakes, MBIE states that, if the floor plate of the dwelling is not strong enough, lateral spreading may cause an extension of the floor plate (that is, the concrete floor slab may crack or the timber floor may fracture generally at joints between framing members).

El desarrollo de nuevos reglamentos de diseño de estructuras sismorresistentes ha hecho posible que se garantice un mejor comportamiento de los edificios cuando éstos son sometidos a acciones sísmicas. Multiple points of strengths and redundancies share the force instead of the quake splitting the foundation apart. Lateral movement occurs when earthquake shaking causes a mass of soil to lose cohesion and move relative to the surrounding soil. In this situation, the weight of the soil block, often in combination with the destabilising effect of groundwater and/or seismic shaking, exceeds the shear strength of the ground.

They have to appreciate multiple factors they may not be experts in and communicate with other professionals to find the most effective solutions. Buildings designed to withstand violent earthquakes have deep foundations and driven piles. In contrast, the procedures used in US codes may not provide a clear view for seismic response assessment of buildings. The aim of this study is to analyze the transparency of earthquake-resistant design approach for buildings in Mexico by means of a critical review of the factors for strength modification and displacement amplification. To stabilize these drastic measures, the foundations are connected so they move as a unit. Without considering earthquakes, professionals still focus on a building’s vertical stiffness and strength as it has to support itself. Hernández's research interests include but not limited to seismic analysis and design of highway bridges, laboratory testing of reinforced and prestressed concrete members. A stable foundation is a major characteristic of building a large structure regardless of natural disaster risks. He received his M.Sc. Tying into the stable foundation characteristic, structural and nonstructural components of a building need to be interconnected so inertial forces dissipate. He worked for 6 years as a design engineer, designing various reinforced concrete structures.
