Bridges that cross faults are subject to static deformation that occurs at almost the same time as the arrival of dynamic pulse-like ground motions. Static offsets can be as large as several centimeters to many meters and strong ground motion velocity pulses exceeding 100 cm/s have been observed. Near-fault records, in the distance range of 10 to 100s of meters from faults are essentially nonexistent except for a few cases and therefore numerical simulation of ground motions for such near-fault situations is necessary. The paper presents simulated ground motions to 17.5 Hz, 15-100m from the fault for a Mw6.5 earthquake using an elastic finite-difference code. Simulations for homogeneous earth structure are compared for uniform and heterogeneous fault rupture scenarios. To investigate asymmetry of ground motions on opposite sides of a dipping reverse fault the dislocation method of Okada (1992) is used to compute static offset. From those results a simplified procedure for the simulation of near-fault time histories is developed. All of the simulations assume linear elasticity, and it is noted that the computed strain is as high as 10-4 - 10-3, and it is likely that there would be significant non-linear behavior in this near-fault region.

Secondary Moments of Continuous Prestressed Concrete Beams Using Closed Form Equation
ASCE Conf. Proc. doi:10.1061/41031(341)22
Venketaramani Tiruchirapalli1 and Riyadh Hindi, Ph.D., P.Eng.2
ISBN:
978-0-7844-1031-8
Abstract:
This paper provides practical engineers with an equation to calculate the secondary moments of prestressed concrete continuous beams. Normally the prestressed secondary moments are calculated by deriving it from the net moment and the primary moments. This involves extensive calculations and sometimes complex integration techniques but the proposed equation described in this paper will give the secondary moment directly. The secondary moment calculated using the equation is compared with the secondary moment calculated using various existing methods such as support displacement method, moment distribution method and stiffness method, and also using the structural analysis software STAAD. For the purpose of analysis, two span, three span and four span beams are considered. This equation can be applied to multiple span beams/girders. Finally the equation is used to show the principle of concordant profile where the secondary moments are zero at the intermediate supports.

Product Description
The Eco2 Cities approach is a point of departure for cities that would like to reap the many benefits of ecological and economic sustainability. It provides an analytical and operational framework that offers strategic guidance to cities on sustainable and integrated urban development. At the same time case studies are used throughout the book to provide a matter-of-fact and ground-level perspective. The Eco2 framework is flexible and easily customized to the context of each country or city. Based on the particular circumstances and the development priorities of a city – the application of the framework can contribute to the development of a unique action plan or roadmap in each case. This action plan can be triggered through catalyst projects.
To support this framework, the book also begins to introduce some powerful and practical methods and tools that can further enable sustainable and integrated city planning and decision making. These include 1) operational and process methods that can strengthen collaborative decision making and cross-sector synergies in a city; 2) analytical methods ranging from diagnostics, simulation, design and scenario-generation; and 3) accounting and benchmarking methods which can help clarify, define and measure what it means to truly invest in sustainability and resilience.
As additional reference reading, the book also features a series of case studies from best practice cities around the world, each demonstrating a very different dimension of the Eco2 approach. It also features a series of infrastructure sector notes (on spatial development, transport, energy, water and waste management), each of which explore sector specific issues as they pertain to urban development, and the many opportunities for coordination and integration across sectors.

The role of an airport within the air transport system used to be largely incontestable. The system is now being shaped less by the concept of social service and more by market forces. Progressive liberalisation of air transport, together with trends to privatisation and globalisation are causing the roles of airports to change, for planning to become increasingly decentralised, and for the traffic to become more volatile. Airports are increasingly in competition for markets. Yet the markets are limited, and airport expansion is made difficult by environmental pressures that push towards sustainable transport, and the need to justify investment. The book will examine these pressures in order to identify changes that are required to the airport planning process. The major issues to be discussed are: forecasting in an uncertain world; airport market share; airline network choices; political settings and their consequences; economic justification and viability; environmental impacts and their mitigation; cooperative planning; and physical planning challenges. The issues will be illuminated by case studies of representative airport systems: intercontinental gateways, metropolitan multi airport system, provincial and regional airports and developing country systems. The final section will bring together suggestions for ways in which the industry can move forward to a green and profitable future with an appropriate provision of new capacity.

The Structural Design of Air Gas Ducts for Power Stations Industrial Boilers Applications
Size: 14.67 MB | Format:PDF | pages: 55
This document, "The Structural Design of Air and Gas Ducts for Power Stations and Industrial Boiler Applications", has been created to assist structural engineers when performing the structural analysis and design of ductwork. Air and gas ducts for fossil fuel power stations and industrial boiler applications are unique structures. Considering that ductwork structural analysis and design is not currently referenced or governed by any national code or design standards, this publication presents the structural engineer with current approaches for the structural analysis and design of air and flue-gas ductwork. Included are sections on: Material selection, behavior and performance; design loads, loading combinations and allowable stresses; thermal considerations; vibration considerations; structural arrangement and behavior; toggle duct behavior and expansion joint considerations; overall duct structural analysis and design methods; and design considerations for local elements of the structure, such as stiffeners, internal braces, connections, turning vanes, and other flow distribution devices. This document also discusses drawing and specification content, fabrication and construction techniques and considerations, duct support methods, and special considerations regarding the design of duct support structures. Finally, it talks about field maintenance examinations and inspections for the purpose of preventative maintenance or condition assessment.
