Curtain Wall Systems: A Primer provides a comprehensive introduction to the use of curtain wall systems in building envelopes. Today’s curtain wall systems go beyond the basic functions of providing natural lighting and protecting the building interior from the external environment. These systems now are expected to conserve energy and ensure occupant comfort by controlling heat flow and solar radiation. Moreover, curtain wall systems must be designed for acceptable performance under natural disasters and human-made hazards. The design, fabrication, construction, and maintenance of advanced and efficient curtain wall systems demand the involvement of professionals from several fields of engineering and building technology. This Manual of Practice compiles a basic review of the many aspects of curtain wall systems that affect their design and performance. It highlights the materials used to manufacture curtain walls for low-rise to high-rise construction and describes different types of tests, mockups, and inspections. Methods of improving the energy performance, waterproofing, and wind loading of curtain walls are assessed. Specialised aspects of curtain wall design and analysis for extreme events, such as earthquake and bomb blast, are explored. Innovative façade design and new curtain wall and glazing systems are covered as well. MOP 126 is written for architects, structural engineers, HVAC engineers, general contractors, building owners, and building operators who are new to curtain wall systems and want to learn more about this specialised and emerging field. Prepared by the Committee on Curtain Wall Systems of the Architectural Engineering Institute of ASCE.

Sponsored by the Pipelines Division of the Utility Engineering and Surveying Institute of the American Society of Civil EngineersWater Pipeline Condition Assessment provides water utilities with an appropriate path for determining the structural status of an individual pipeline or pipeline system. Such condition assessments form a critical piece of an effective asset management program by establishing a baseline to understand the present state of a pipeline. By recognizing that current state, the asset management program then enables the water utility to anticipate future issues and allocate the appropriate measures to be undertaken to provide for the continuous safe and reliable operation of the system.This manual of practice focuses on the larger diameter transmission pipelines of water utilities, rather than the smaller diameter distribution systems. It provides technical information and recommendations to set priorities and obtain an accurate determination of the condition of the individual pipelines and pipeline systems. MOP 134 discusses data collection and management, planning, tools/technologies, and the condition assessment report. Six pipe materials are explained in detail: cast iron and ductile iron, concrete, steel, fiberglass, polyvinyl chloride, and asbestos cement. Seven case studies of projects in California, Florida, Texas, and Utah demonstrate the application of a variety of technologies for condition assessment.MOP 134 will be a valuable reference for operators, engineers, managers, and regulators of water utilities interested in the value of condition assessment as part of an overall asset management program.

Prepared by the Task Committee to Revise Guidelines for Dam Instrumentation of the Committee on Water Power of the Energy Division of ASCE.Monitoring Dam Performance: Instrumentation and Measurements presents the fundamentals and current state of practice of instrumented measurements for monitoring dam performance.  Dam performance monitoring is a balance of visual surveillance and instrumental measurements to accurately understand how well a dam is performing. Mechanical, electromechanical, and electronic instruments are used to measure geotechnical, structural, hydraulic, or geohydrologic dam performance indicators that are not observable by visual surveillance. Performance monitoring as part of a comprehensive dam safety program is a powerful tool for identifying and managing the risk of failure associated with a dam. Instrumented monitoring produces quantitative data regarding foundation, reservoir, tailwater, and precipitation conditions surrounding and within the dam. Instrumented monitoring can provide long-term records of data, allowing for detection of time or load-dependent trends in a dam’s performance. MOP 135 delves into embankment, concrete, and other types of dams. It also examines their possible vulnerabilities, as well as explores how their potential modes of failure lead to asking performance questions that instrumented measurements can help monitor. This manual of practice covers

Prepared by the Fire Protection Committee of the Structural Engineering Institute of ASCEStructural Fire Engineering provides best practices for the field of performance-based structural fire engineering design. When structural systems are heated by fire, they experience thermal effects that are not contemplated by conventional structural engineering design. Traditionally, structural fire protection is prescribed for structures after they have been optimized for ambient design loads, such as gravity, wind, and seismic, among others. This century-old prescriptive framework endeavors to reduce the heating of individual structural components with the intent of mitigating the risk of structural failure under fire exposure. Accordingly, the vulnerability of buildings to structural failure from uncontrolled fire varies across jurisdictions–which have differing structural design requirements for ambient loads–and as a function of building system and component configuration. As an alternative approach, Standard ASCE 7-16 permits the application of performance-based structural fire design (also termed structural fire engineering design) to evaluate the performance of structural systems explicitly under fire exposure in a similar manner as other design loads are treated in structural engineering practice.Structural fire engineering design is the calculated design of a structure to withstand the thermal load effects of fire, which have the potential to alter the integrity of a structure, based on specific performance criteria. This manual, MOP 138, addresses the current practice, thermal and structural analysis methods, and available information to support structural fire engineering design. It covers:Background information on the protection of structures from fire and the effects of fire on different types of construction,Key distinctions between standard fire resistance design and structural fire engineering design,Guidance for evaluating thermal boundary conditions on a structure because of fire exposure and on conducting heat transfer calculations based on the material thermal properties,Performance objectives for structures under fire exposure, andAnalysis techniques that can be used to quantify structural response to fire effects.This Manual of Practice is a valuable resource for structural engineers, architects, building officials, and academics concerned with performance-based design for structural fire safety.

Radar-derived rainfall estimation is one of the most significant recent advances in hydrologic engineering and practice. Rain gauges provide point values of rainfall depth and intensity but are not cost effective in providing information about the spatial distribution of rainfall, whereas radar-derived rainfall data provides a density of measurements that are not obtainable by rain gauges alone. Combining these two sensor systems produces better rainfall estimates that more accurately characterize rainfall across a watershed. This Manual of Practice provides a framework for researchers and practicing engineers working in hydrologic engineering to develop radar rainfall data sets and analyze them according to their varied goals and resources. Topics includeAn introduction to and examples of radar rainfall estimation, Temporal and spatial characteristics of radar rainfall data,Methodology for radar rainfall data quality evaluation and improvement,Use of radar rainfall data in hydrologic modeling,Rainfall data augmentation and design of rainfall monitoring networks, andExamples of radar rainfall data analysis and data applications.MOP 139 will be a valuable resource for government agencies, a framework for engineering firms, practicing engineers, researchers, and students working in the hydrologic engineering field.
