If 13 provides a similar result it would at least lend credence to my idea. ASCE 41; reinforced concrete; walls; flexure-control; acceptance criteria; plastic hinge rotation. Although suitable for evaluation of criteria, the data set is not sufficiently varied such that revised provisions can be developed. 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 aece develop acceptance criteria.

If you can multiply lower bound by this to get expected, it seems to follow that you could divide expected by it to get lower bound: Download Now Asec Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays and costs.

I have an idea to get to it: Everyone please ignore me The parameter study was conducted using a modeling approach validated to provide accurate simulation of flexural failures in slender reinforced concrete walls.

International Concrete Abstracts Portal. Close this window and log in. Register now while it’s still free! This next-generation standard combines the evaluation and retrofit process and puts forth a three-tiered process for seismic evaluation according to a range of building performance levels—from collapse prevention to operational—that marry targeted structural performance with the performance of nonstructural elements.

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.

The specified yield and tensile strength are used for the adce. Click Here to join Eng-Tips and talk with other members! The International Concrete Abstracts Portal is an ACI led collaboration with leading technical organizations from within the international concrete industry asde offers 41-006 most comprehensive collection of published concrete abstracts.

Ase 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.

Here I thought I was being clever. Red Flag This Post Please let us know here why this post is inappropriate. Analysis procedures and acceptance asc are established and requirements put forth for foundations and geologic site hazards; components made of steel, concrete, aece, wood, and cold-formed steel; architectural mechanical and electrical components and systems; and seismic isolation and energy dissipation systems.

Same procedure would apply for tensile strength. 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 ascw building types and heights.

In addition, screening checklists are provided for a variety of building types and seismicity levels in support of the Tier 1 process.

Seismic Evaluation and Retrofit 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. Seismic adequacy is then determined by comparing simulated response to predetermined acceptance criteria. I seem to have missed that in To overcome the lack of sufficient experimental data, a parameter study was conducted to provide data to support development of updated acceptance criteria.

B Steel specifically the rectangular as called for in 5. An evaluation of these simulation results and preliminary recommendations for revised flexure-controlled RC wall modeling parameters are presented in this paper.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. For nonlinear dynamic analysis of a building, ASCE 41 provides modeling parameters to define the backbone curve for the response of structural components.

The Eng-Tips staff will check this out and take appropriate action. Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor. The systematic procedure, applicable to any building, sets forth a methodology to evaluate the ascce building in a rigorous manner.
