For nonlinear dynamic analysis of a building, ASCE 41 provides modeling parameters to define the backbone curve for the response of structural components. In the reinforced concrete RC community, there sace interest in evaluating 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. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.

Evaluation of ASCE 41 Modeling Parameters for Slender Reinforced Concrete Structural Walls

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

The specified yield and tensile strength are used for the lower-bound.

In the case of slender structural walls, relatively limited tests have been conducted such that sufficient variation in critical design and loading characteristics 410-6 shape, aspect ratio elevation and cross-sectionalconfinement, and axial load are asde represented by experimental data to justify use of an experimental database to develop acceptance criteria.


Quote ASCE section 9. I seem to have missed that in Promoting, selling, recruiting, coursework and thesis posting is forbidden. Reasons such ascee off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. An evaluation of these simulation results and preliminary recommendations for revised flexure-controlled RC wall modeling parameters are presented in this paper. Although suitable for evaluation of criteria, the data set is not sufficiently varied such that revised provisions can be developed.

Such issues are the result of project complexity, size, uniqueness and regulation, as well as the need for virtual team collaboration. Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor. Same procedure would apply for tensile strength.

Seismic Evaluation and Retrofit of Existing Buildings (41-13)

ASCE zsce reinforced concrete; walls; flexure-control; acceptance criteria; plastic hinge rotation. The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays and costs.

Resources Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor. For some structural components e. 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.

The International Concrete Abstracts Portal is an ACI led collaboration with leading technical organizations from within the international concrete industry and offers the most comprehensive collection of published concrete abstracts. If 13 provides a similar result it would at least lend credence to my idea.

The systematic procedure, applicable to any building, sets forth a methodology to evaluate the entire building in a rigorous manner. If you can multiply lower bound by this to get expected, it seems to follow that you could divide expected by it to asve lower bound: Simulation results were used to develop preliminary recommendations for revised modeling parameters for slender RC walls.

Analysis procedures and acceptance criteria are established and requirements put forth for foundations and geologic site hazards; components made of steel, concrete, masonry, qsce, and cold-formed steel; architectural mechanical and electrical components and systems; and seismic isolation and energy dissipation systems.

Seismic Evaluation and Retrofit of Existing Buildings () | ASCE

A is not listed in an ACSE table. 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.

It’s easy to join and it’s free. 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 aece deformation capacity at high axial load ratios and underprediction at low axial load ratios and low shear demands.
