Minimum Design Loads for Buildings and Other Structures provides requirements for general structural design and includes means for determining dead, live, soil, flood, wind, snow, rain, atmospheric ice, and earthquake loads, as well as their combinations, which are suitable for inclusion in building codes and other documents. This Standard, a revision of ASCE/SEI 7-05, offers a complete update and reorganization of the wind load provisions, expanding them from one chapter into six. The Standard contains new ultimate event wind maps with corresponding reductions in load factors, so that the loads are not affected, and updates the seismic loads with new risk-targeted seismic maps. The snow, live, and atmospheric icing provisions are updated as well. In addition, the Standard includes a detailed Commentary with explanatory and supplementary information designed to assist building code committees and regulatory authorities. Standard ASCE/SEI 7 is an integral part of building codes in the United States. Many of the load provisions are substantially adopted by reference in the International Building Code and the NFPA 5000 Building Construction and Safety Code. Structural engineers, architects, and those engaged in preparing and administering local building codes will find this Standard an essential reference in their practice. Note: New orders are fulfilled from the second printing, which incorporates the errata to the first printing.

Fundamentals of earthquake engineering

This paper presents some of the oral discussion by the author and others at the 2005 Annual Meeting of the Los Angeles Tall Buildings Structural Design Council. It also includes additional opinions added by the author after the annual meeting. These opinions address the development of a new building code for tall buildings and where the non-structural engineering decision makers can and must make contributions. It also addresses the very important topic of quality control. Copyright © 2005 John Wiley & Sons, Ltd.

Endurance time method is a time history dynamic analysis in which structures are subjected to predesigned intensifying excitations. This method provides a tool for response prediction that correlates structural responses to the intensity of earthquakes with a considerably less computational demand as compared to conventional time history analysis. The endurance time method is being used in different areas of earthquake engineering such as performance-based assessment and design, life-cycle cost-based design, value-based design, seismic safety, seismic assessment, and multicomponent seismic analysis. Successful implementation of the endurance time method relies heavily on the quality of endurance time excitations. In this paper, a review of the endurance time method from conceptual development to its practical applications is provided. Different types of endurance time excitations are described. Features related to the existing endurance time excitations are also presented. Particular attention is given to different applications of the endurance time method in the field of earthquake engineering.

A state-of-knowledge review on the Endurance Time Method

This paper uses the value-based seismic design methodology to optimize the mechanical and geometrical properties of triple friction pendulum bearings (TFPBs). An optimization procedure is proposed within this methodology. Initial construction cost and lifetime seismic losses are picked as the value components. Extreme failure conditions of the TFPB, less considered in the current literature, such as the uplift and exit failure modes of the curved surface sliders at the end edges, have been carefully considered in the seismic behavior of the structure. Besides, the minimum code provisions and practical limitations (e.g., the critical overturning diameter of sliders) for friction pendulum isolated buildings are regarded as design constraints. Moreover, a new cost function for TFPBs is developed from real projects of isolated buildings. The FEMA P-58 procedure is exploited to evaluate the lifetime seismic repercussions, comprising the reparation cost, reparation time, injuries, and fatalities. The endurance time method is incorporated in the FEMA P-58 procedure to estimate the structural seismic responses. A set of three buildings are chosen for evaluation, representing low-to mid-rise isolated moment-resisting frames (MRFs) with TFPBs. Each building is optimally designed with two approaches: the value-based design (VBD) via maximizing the total building value and the code-based design (CBD) via minimizing the construction cost. It is found that the total value of each isolated MRF building optimized using the CBD approach is moderately acceptable. Nevertheless, it can be notably increased using the VBD approach since it sufficiently diminishes the probability of the uplift and exit failure modes at the end edges of TFPBs.
