TL;DR: In this paper, the effects of plan asymmetry on the earthquake response of code-designed, one-story systems are identified with the objective of evaluating how well these effects are represented by torsional provisions in US building codes.
Abstract: The effects of plan asymmetry on the earthquake response of code-designed, one-story systems are identified with the objective of evaluating how well these effects are represented by torsional provisions in US building codes. The earthquake-induced deformations and ductility demands on resisting elements of asymmetric-plan systems, are compared with their values if the system plan were symmetric. The presented results demonstrated that the design eccentricity in US building codes should be modified in order to achieve the desirable goal of similar ductility demands on asymmetric-plan and symmetric-plan systems. The design eccentricity should be defined differently depending on the design value of the reduction factor R.

TL;DR: A good deal of New Zealand research and development has led to the current philosophy for the design of structures for earthquake resistance, as expressed by current recommendations of study groups of the New Zealand National Society for Earthquake Engineering and in provisions of recent codes of the Standards Association for New Zealand as mentioned in this paper.
Abstract: Structural design procedures for earthquake resistance in New Zealand have gradually evolved since the 1931 Hawkes Bay earthquake. A good deal of New Zealand research and development has led to the current philosophy for the design of structures for earthquake resistance, as expressed by current recommendations of study groups of the New Zealand National Society for Earthquake Engineering and in provisions of recent codes of the Standards Association of New Zealand. These recommendations and codes emphasize the importance of structural detailing to achieve satisfactory performance of structures during severe seismic loading.

TL;DR: The seismic resistant retrofit design of bridges has been evolving dramatically in the last decade and many of the retrofit concepts and details discussed in this paper have emerged as a result of research efforts and evaluation of bridge behavior in past earthquakes.
Abstract: The seismic resistant retrofit design of bridges has been evolving dramatically in the last decade. Many of the retrofit concepts and details discussed in this paper have emerged as a result of research efforts and evaluation of bridge behavior in past earthquakes. This practice has been successfully tested in relatively moderate earthquakes but has not yet seen the severe test of a large-magnitude earthquake. The basic philosophy of current seismic retrofit technology in the U.S. is to prevent collapse by providing sufficient seat for displacement to take place or by allowing ductility in the supporting members. This paper's aim is to identify potential vulnerabilities to bridge components and to suggest practical retrofit solutions.
