This CTBUH Technical Guide provides structural engineers, developers, and contractors with a general understanding of the PBSD process by presenting case studies that demonstrate the issues commonly encountered when using the methodology, along with their corresponding solutions. The guide also provides references to the latest industry guidelines, as applied in the western United States, with the goal of disseminating these methods to an international audience for the advancement and expansion of PBSD principles worldwide.

OpenFlows WaterGEMS provides you with a comprehensive yet easy-to-use decision-support tool for water distribution networks. The software helps improve your knowledge of how infrastructure behaves as a system, how it reacts to operational strategies, and how it should grow as population and demands increase.
From fire flow and water quality simulations, to criticality and energy cost analysis, OpenFlows WaterGEMS has everything you need in a flexible multiplatform environment.
OpenFlows WaterGEMS provides numerous software capabilities for:
Intelligent planning for system reliability: The capability of the water network to adequately serve its customers must be evaluated whenever system growth is anticipated. With OpenFlows WaterGEMS, effectively identify potential problem areas, accommodate service area growth, and plan capital improvements.
Optimized operations for system efficiency: Realistically modeling the operation of complex water systems can be difficult. With OpenFlows WaterGEMS, model pumps accurately, optimize pumping strategies, and plan shutdowns and routine operations to minimize disruption.
Reliable asset renewal decision support for system sustainability: When it comes time to renew or replace your water infrastructure, the amount of asset-related information you must consider can be overwhelming. OpenFlows WaterGEMS capabilities such as Pipe Renewal Planner makes the task much easier by analyzing and comparing a wide range of variables to prioritize renewal decisions.
OpenFlows WaterGEMS is a superset of OpenFlows WaterCAD.

Problems in nonlinear structural dynamics and critical excitation with elastic-plastic structures are typically addressed using time-history response analysis, which requires multiple repetitions and advanced computing. This alternative approach transforms ground motion into impulses and takes an energy balance approach.
This book is accessible to undergraduates, being based on the energy balance law and the concepts of kinetic and strain energies, and it can be used by practitioners for building and structural design. This presentation starts with simple models that explain the essential features and extends in a step-by-step manner to more complicated models and phenomena.

This document defines the minimum experimental evidence that can be deemed adequate to attempt to validate the use, in regions of high seismic risk or in structures assigned to satisfy high seismic performance or design categories, of weak beam/strong column moment frames not satisfying fully the prescriptive requirements of Chapter 21 of ACI 318-99. This document consists of both a Standard and a Commentary that is not part of the Standard. The document has been written in such a form that its various parts can be adopted directly into Sections 21.0, 21.1, and 21.2.1 of ACI 318-99 and the corresponding sections of ACI 318R-99. Among the subjects covered are requirements for: procedures that shall be used to design test modules; configurations for those modules; test methods; test reports; and determination of satisfactory performance.
The Commentary describes some of the considerations of the Innovation Task Group in developing the Standard. The section numbering for the Commentary is the same as that for the Standard, with numbers preceded by an “R” to distinguish them from the corresponding section numbers of the Standard.
The Commentary references documentary evidence, additional to the references of Chapter 21 of ACI 318R-99, that supports the Standard. Consistent with the approach of ACI 318-99 and ACI 318R-99, no comparison is made, either in the body of the Standard or its Commentary, of research results for test modules satisfying ACI 318-99 with those for modules that, although not satisfying ACI 318-99, do satisfy the Standard. Such comparisons, both experimental and analytical, are available in the references of the Commentary.
Keywords: acceptance criteria; drift ratio; energy dissipation; lateral resistance;
moment frame; post-tensioning; precast concrete; prestressed concrete; seismic design; test module; toughness.
