A task committee comprised of local structural engineers and earthquake engineering experts from abroad was formed to assess the seismic performance of public schools in under auspices of this group; a guideline has been developed better assess the existing conditions and develop retrofit options for school and hospital buildings in […]
Seismic Retrofit of Historic Iasi City Hall Building Using Seismic Protective Devices
Romania’s Iasi City Hall was originally constructed in the 1810’s in neo-classical Viennese style. It was modified in 1860’s and turned to the city hall in 1891. It is considered a cultural heritage building and was the Romanian Royal Family residence. The building framing is comprised of reinforced concrete floors, […]
Massive Damage Assessment Program and Repair and Reconstruction Strategy in the Aftermath of the 2010 Haiti Earthquake
The January 2010 Haiti earthquake resulted in over 230,000 deaths, affected 3 million people, and damaged or collapsed over 200,000 structures. An unprecedented earthquake damage assessment project by a joint operation of the Haitian Ministry of Public Works, the United Nations Office of Project Services, the Pan American Development Foundation, […]
Identifying the Collapse Hazard of Steel Special Moment-Frame Buildings with Viscous Dampers Using the FEMA P695 Methodology
An innovative design using steel special moment frames sized per building code requirements for strength and viscous dampers to control story drift ratios results in longer period structures that limit floor accelerations with excellent performance in design-level earthquakes. However, the response of this design to extreme seismic events is not […]
Structural Control of Dynamic Blast Loading
H. Kit Miyamoto and Douglas Taylor ASCE Conf. Proc. 103, 116 (2000) For full access to this technical paper click here and we will contact you shortly. The purpose of this paper is to evaluate the effectiveness of Fluid Viscous Dampers (FVD) when used to control blast loading responses on lateral load resisting […]
Performance of Structures with Passive Energy Dissipators
The purpose of this paper is to evaluate the earthquake performance of structures with passive energy dissipators. This paper addresses the following issues: (1) evaluation of seismic intensity levels at which frames incorporating the energy dissipating system (EDS) remain elastic; (2) performance evaluation of frames incorporating an EDS for high-intensity […]
Seismic Evaluation and Upgrade of Historic Multi‐Story Buildings in Sacramento, California
Structural performances of two historic high‐rise buildings, constructed in the early 1920s and located in seismic zone 3 in downtown Sacramento, CA were investigated. The objectives of this evaluation were to determine whether these structures met the current seismic criteria and to propose strategies to upgrade such performance to an […]
Seismic Rehabilitation of a Nine‐Story Hospital Building Using Fluid Viscous Dampers
Analytical investigations were undertaken to assess the seismic performance of a hospital building located in Southern California in seismic zone 4. The structure consists of a eight‐story steel, and a bottom story reinforced concrete superstructure constructed over four levels of sub‐grade parking stories. The building is rectangular, is 125 ft […]
Comprehensive Evaluation and Seismic Retrofit of a Three‐Story Non‐Ductile Concrete Structure
Performance‐based earthquake engineering was utilized to ascertain the seismic performance of an existing two‐story non‐ductile reinforced concrete building with a proposed new third floor steel‐framed addition. The structure, hereafter referred to as the Capital Unity Center, is located in downtown Sacramento. California, and was designed and constructed in early 1940s […]
Seismic Retrofit of a Hospital Building with Supplementary Damping Devices
Performance‐based earthquake engineering was utilized to ascertain the seismic performance of a group of hospital buildings located in the regions of high seismicity in Southern California. The structures were designed and constructed in early 1970’s per the applicable building codes at the time of construction. Seismic evaluation of the structures, […]
