The historic Lane Building is a twelve-story, nonductile concrete structure originally constructed in the early 1920s. The owner undertook a renovation project to convert the building to a mixed-use property with ground-floor retail and more than...
Northeastern University wanted to construct a cold spray laboratory for metal and plastics coating and repair at Kostas Research Institute. They needed to know if the existing structure could accommodate the new facility. SGH evaluated the...
In the mid-1990s, the Federal Emergency Management Agency (FEMA) supported a joint effort of the Applied Technology Council (ATC), American Society of Civil Engineers, and Building Seismic Safety Council to develop seismic retrofit design...
Constructed in 1969, this two-story building houses administrative offices and the school library. As part of a campus modernization project, Glendale High School wanted to mitigate the seismic deficiencies resulting from a soft-story...
SGH was the engineer of record for the seismic retrofit design of two 450 ft long wharf structures that required strengthening to comply with the MOTEMS seismic performance standards for marine oil terminals in the state. SGH developed an...
Commercial building designs have long incorporated exterior soffits, better known outside of the building design and construction industry as the underside of any projecting building feature. Aside from soffits at the eave or rake edges of a...
We, as structural engineers, often find ourselves confined by a situation we created for ourselves. We operate in a design environment with easy access to information, have the ability to collect and analyze extensive data, and have access to...
Structural systems protected with qualified assemblies according to prescriptive methods may be resistant to heating during fire events, but they are not specifically designed to endure thermal load effects. The emerging field of structural fire...

The ASCE/SEI Technical Committee on Fire Protection was formed to support professional structural engineers conducting performance-based design of structural systems for fire effects with guidance documents. The Committee saw a need for an ASCE/...
ABSTRACT
There is a recognized need for international guidelines associated with the design and assessment/maintenance of marine oil and petrochemical terminals. The very nature of the marine oil and petrochemical trade is...
Abstract: A sustainable roof must perform its primary purpose of protecting the building reliably and for the duration of its planned service life. The potential environmental burden created by premature roofing failure or its unplanned...
The authors employed high-fidelity computer modeling to analyze the probable seismic performance of an existing high-rise, steel frame building with unreinforced masonry infill walls in downtown San Francisco. The Pacific Telephone and Telegraph...
Abstract: Since its inception, the purpose of the ASCE 7 standard has been to set minimum design loads for buildings and other structures, such that they would provide safe and reliable service. It has never been intended to comprise a complete...
Simpson Gumpertz & Heger has prepared two prototypical designs for a 40-story buckling-restrained braced steel-framed office building located at a generic site in Los Angeles, CA. One of these designs conforms in all respects, except height...
Abstract: Performance-based seismic design methods in the United States originated as a practical and effective means to mitigate the seismic risks posed by existing buildings and were later extended to permit development of new buildings capable...
