strategies are proposed following the ASCE/SEI guidelines. To minimize retrofit cost, Nonlinear Static. Procedure is adopted because it provides a more. to update two national standards: ASCE “Seismic Evaluation of Existing Buildings” and ASCE. “Seismic Rehabilitation of Existing Buildings.

Simulation results were used to develop preliminary recommendations for revised modeling parameters for slender RC walls. Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor.
Analysis procedures and acceptance criteria are established and requirements put forth for foundations and geologic site hazards; components made of steel, concrete, masonry, wood, and cold-formed steel; architectural mechanical and electrical components and systems; and seismic isolation and energy dissipation systems.
Evaluation of ASCE 41 Modeling Parameters for Slender Reinforced Concrete Structural Walls
It provides a factor 4-106 1. By joining you are opting in to receive e-mail. The deficiency-based procedures allow the evaluation and retrofit effort to focus on specific potential deficiencies deemed, on the basis of past earthquake observations, to be of concern for a permissible set of building types and heights.
I’ve reviewed the ASTM Specification for a few of the listed materials and for A, but I can’t see how it could have been derived from any of that.
The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays and costs. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.
Seismic Evaluation and Retrofit of Existing Buildings (41-13)
Same procedure would apply for tensile strength. Red Flag This Post Please let us know here why this post is inappropriate. Seismic Evaluation and Ascr of Existing Buildings describes deficiency-based and systematic procedures that use performance-based principles to evaluate and retrofit existing buildings to withstand the effects of earthquakes. Such issues are the result of project complexity, 41-006, uniqueness and regulation, as well as the need for virtual team collaboration.
For nonlinear dynamic analysis of a building, ASCE 41 provides modeling parameters to define the backbone curve for the response of structural components. ASCE 41; reinforced concrete; walls; flexure-control; acceptance criteria; plastic hinge rotation.

Everyone please ignore me Seismic adequacy is then determined by comparing simulated response to predetermined acceptance criteria. Join your peers on the Internet’s largest technical engineering professional community.
Resources Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor. An evaluation of these simulation results and preliminary recommendations for revised flexure-controlled RC wall modeling parameters are presented in this paper.
In the reinforced concrete RC community, there is interest in ascd the modeling parameters and acceptance criteria for RC components, and if deemed necessary, developing updated values that reflect the current state of understanding of the seismic performance of RC components.
The Eng-Tips staff will check this out and take appropriate action. B Steel specifically the rectangular as called for in 5. Evaluation of this limited set of experimental data indicates current ASCE 41 modeling parameters and acceptance criteria for flexure-controlled walls is inappropriate, generally resulting in overprediction of wall deformation capacity at high axial load ratios and underprediction at low axial load ratios and low shear demands.
In addition, screening checklists are provided for a variety of building types and seismicity levels in support of the Tier 1 process. The systematic procedure, applicable to any building, sets forth a methodology to evaluate the entire building in a rigorous manner.

I have an idea to get to it: If 13 provides a similar result it would at least lend credence to my idea. Students Click Here Join Ascce
Download Now The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage 14-06 project delays and costs. Although suitable for evaluation of criteria, the data set is not sufficiently varied such that revised provisions can be developed.
To overcome the lack of sufficient experimental data, a parameter study was conducted to provide data to support development of updated acceptance criteria. Here I thought I was being clever. I seem to have missed that in It’s easy to join and it’s free. In the case of slender structural walls, relatively limited tests have been conducted such that sufficient variation in critical design and loading characteristics including shape, aspect ratio elevation and cross-sectionalconfinement, and axial load are not represented by experimental data to justify use of an experimental database to develop acceptance criteria.

Promoting, selling, recruiting, coursework and thesis posting is forbidden. The parameter study was conducted using a modeling approach validated to provide accurate simulation of flexural failures in slender reinforced concrete walls.
The specified yield and tensile strength are used for the lower-bound.
