ASCE/SEI 74-23, is intended for use in the design of new buildings and other structures constructed of pultruded fiber–reinforced polymer (FRP) composite structural shapes, connections, and prefabricated building products. It addresses pultruded FRP structural shapes that have symmetric and balanced glass reinforcement and fiber architecture combined with a polymeric matrix.

ANSI/ASCE/EWRI 33-23, serves as a comprehensive framework designed to assist riparian governments in effectively managing shared water resources. This agreement offers practical guidance for national and state governments, as well as other stakeholders involved in establishing water quality standards for sustainable management of transboundary water resources.

Standard 39-23, provides a general overview of the science and technology of hail suppression combined with specific strategies and procedures required to design, conduct, and evaluate hail suppression operations. Such operational activities as airborne, ground-based, and rocket and artillery delivery systems are addressed. The standard includes both mandatory and advisory provisions.

This new digital interactive platform launches with ASCE/SEI 7-22, 7-16, 7-10, and ASCE/SEI 41-23, plus Tier 1 Checklists. The complete Provisions and Commentary of the standards are available within a suite of interactive tools and feature-rich functionality that make working in each standard an easier experience for the engineer. Additional standards and materials will be added on a rolling basis.

Benefit from the one-click synchronization between Provisions and Commentary with side-by-side display, red-lining, two-level search functionality, real-time incorporation of supplements and errata, and more.

Seismic Evaluation and Retrofit of Existing Buildings, Standard ASCE/SEI 41-23, describes deficiency-based and systematic procedures that use performance-based principles to evaluate and retrofit existing buildings to withstand the effects of earthquakes. The standard presents a three-tiered process for seismic evaluation according to a range of building performance levels by connecting targeted structural performance and the performance of nonstructural components with seismic hazard levels. The deficiency-based procedures allow evaluation and retrofit efforts to focus on specific potential deficiencies deemed to be of concern for a specified set of building types and heights. The systematic procedure, applicable to any building, sets forth a methodology to evaluate the entire building in a rigorous manner.

Tier 1 Checklists for Seismic Evaluation and Retrofit of Existing Buildings: Fillable Forms for Standard ASCE/SEI 41-23 is a complete collection of the screening checklists included in Chapter 17 and Appendix C of Standard 41-23. The evaluation checklists, covering a variety of building types and seismicity levels, are offered as fillable PDF forms that can be completed using Adobe Acrobat Reader, version 9.0 or later.

The collection of 39 forms includes the summary data sheet, Collapse Prevention and Immediate Occupancy checklists, and a nonstructural checklist. The checklists contain criteria for very low, low/moderate, and high seismicity levels.
