Fort Mason Pier Two Seismic Retrofit and Structural Repair The seismic retrofit and structural repair of Pier 2 at Lower Fort Mason was approved in and the work was completed by The project was needed because the pier was susceptible to seismic damage and possible collapse in the event of a major earthquake.

Fort Mason Pier 2 Rehabilitation San Francisco, CA Photos: Photos: LMS, Historic Archive, Bruce Damonte The project involved renovation and repair of exterior concrete shear walls in a marine environment. R+C provided structural engineering services for the project and recently completed tenant improvements within the building for the San.

the seismic behavior of the stone masonry pier in its existing condition (without retrofit measures). Case 2 analyzed the pier strengthened with 20 mini-piles (refer to Figure 2). For Case 3, the assumptions used were the same as those in Case 1 except that the vertical mortar joints pattern was assumed to run parallel and continuously.

Case 3 is.

RETROFIT OF UNREINFORCED MASONRY BUILDINGS: THE STATE-OF-THE-ART Yasser Korany 1, Robert Drysdale 2, Samir Chidiac3 ABSTRACT The vulnerability of unreinforced masonry buildings to impaired performance is a serious problem facing structural engineers today.

Unreinforced masonry (URM) walls usually. A research study was performed to evaluate two seismic retrofit schemes proposed “Structural Seismic Retrofits for Hawaii Single. 2 Three timber frames were built to test the performance of the post and pier retrofit schemes.

A control specimen was constructed and. FORT MASON CENTER PIER 2 IMPROVEMENT PLAN Project History: Inthe Foundation applied for a grant from the Conservancy to undertake a planning project to develop interpretive signs and displays informing visitors of the lively and interesting history of the area.

The project was approved by the Conservancy on November 9, The Principles and Practice of Effective Seismic Retrofitting This is a very rough draft of a book on retrofitting being written by Howard Cook in collaboration with structural engineers who are members of the Structural Engineer’s Association of Northern California.

It is. Generally, the structural retrofit of concentrically braced frames improved the seismic resistance of the building and it can be considered in the retrofit of moment frame structures to prevent the risk of structural collapse under the design load with much more confidence.

Agency (FEMA) initiated a project on evaluation and repair of earthquake-damaged concrete and masonry wall buildings in The project was conducted Performance-Based Repair Design.

Repair Technologies. Recently developed guidelines for structural engineering seismic analysis and design techniques.

Conventional spread footings are used to support the. • performed a seismic retrofit, • repaired spalling concrete and rusting structural supports, • installed solar power, • installed a in‐floor heating system, • replaced non‐historic exterior doors, and • completed ADA compliance.

Inthe NPS invested $12 million to renovated the Fort Mason pier substructure. Fort. contains relevant information for building offi cials, consulting structural engi-neers and building contractors.

Unreinforced masonry walls do not have a grid of steel reinforcing bars embedded within them. See Chapters 2 and 5 for further description.

Th e typical unreinforced masonry building in the United States has brick walls with no. Project Details. The project consisted of the removal and replacement of all existing concrete spalls on the entire facade of the building exterior. Spall repairs varied from simple small concrete “pop off” repairs to full penetration of existing walls and columns.

The majority of repairs were located on window perimeters and concrete columns. Frame Analysis and Columnar Seismic Forces for Multiple Column Bent – Year Design Earthquake Return Period a. Pier Forces – Dead Load b. Pier Forces from Global Transverse Base Shear c.

Blackstone engineers are experienced in the structural design and retrofit of commercial residential, office and industrial properties, as well as remodel construction for single-family and multi-family wood frame residential properties. More technical details about sub-floor to joist connections.

Let’s Do the Numbers The American Wood Council Online Line Calculator. When we plug variables such as thickness of side member, type of wood, type and thickness of side member into the Online Calculator, we discover that we need a main member (floor) that is thicker than 3/4″ for the L90 to have any value at all.

Fort Mason campus. The project timeline overlapped with the FMC’s $21 million rehabilitation of the Pier 2 shed to establish a Fort Mason campus of the San Francisco Art Institute (SFAI).

However, The SFAI project ending up completing the apron renovation and repaving on Pier 2, as well as slurry coating the Pier 3 apron with other. The seismic performance evaluation and retrofit process are very important in damaged bridges.

If the result is not appropriate, then retrofit process are required. In this paper, to validate the seismic performance of retrofitted bridge experimentally, an experimental study was conducted to verify the application and efficiency of the jacket retrofit method to ensure seismic performance of.

Structural Risks of a Post and Pier House A post-and-pier house is built on wooden posts or concrete piers set into the ground to bear the weight of the house.

Because a post-and-pier house has no continuous concrete-perimeter foundation, it is particularly vulnerable to shifting, and potentially collapsing, in an earthquake. Fort Mason Pier 2 is a former warehouse originally built inand was turned over to the Fort Mason Center nonprofit in to protect the historic structure and supervise its.

Thickness of concrete between pier perimeter and tie rebar (see Figure ). A minimum 3 inch cover is recommended for drilled pier shafts.

If a cover less than 3 inches is used with a permanent casing, the alpha and beta methods used (see Section ) in this procedure may no longer apply. Optimum Seismic has expertise in the retrofitting of masonry buildings as well as the retrofitting of historic buildings.

Fort Mason, once known as San Francisco Port of Embarkation, US Army, in San Francisco, California, is a former United States Army post located in the northern Marina District, alongside San Francisco Mason served as an Army post for more than years, initially as a coastal defense site and subsequently as a military port facility.

Building use and structural classification 12 Prioritisation 12 The potential for synergy in reconstruction and renovation 13 Examination of earthquake safety according to Pre-Standard SIA 13 Decisive factors for seismic retrofit 2 Strategies for seismic retrofitting Recommended strategies POST AND PIER FOUNDATIONS.

The most common problem with post and pier foundations during an earthquake is the tendency of posts to shift off piers and beams to shift off posts. Failure at either of these points can cause the substructure, and sometimes the entire house, to collapse.

But steps can be taken to strengthen post and pier foundations. The team at Optimum Seismic has been providing consultations, engineering, construction and earthquake retrofits for commercial buildings in California since Our experts in seismic engineering, construction management provide quality earthquake retrofit services for all types of commercial buildings.
