NEW RESEARCH REPORT PROVIDES ENHANCED INSIGHTS ON NEWLY DEFINED LATERAL-FORCE RESISTING SYSTEM

FINAL REPORT

Ductile Reinforced Concrete Coupled Walls:
FEMA P695 Study

A code change proposal has been approved for ACI 318-19 Sections 2.3 and 18.10.9 that defines a "Ductile Coupled Wall" as an assembly of walls with aspect ratio of total wall height to length greater than 2.0 which are linked by coupling beams having aspect ratios between 2.0 and 5.0. The aim of this study was to justify the use of the proposed design parameters by applying the FEMA P695 approach to the newly defined lateral system. This report summarizes the design, modeling, and collapse assessment results for the Seismic Design Category being considered for a series of Ductile Coupled Wall configurations representative of common practice.

The Charles Pankow Foundation in partnership with the American Concrete Institute is pleased to share this final report of research grant #06-17 conducted by principal investigator John W. Wallace, Professor and Director, UCLA along with Negin A. Tauberg, Ph.D. Candidate, UCLA and Kristijan Kolozvari, Assistant Professor, CSU Fullerton.

NEW RESEARCH REPORT AIDS DESIGN OF EFFICIENT SEISMIC FORCE-RESISTING SYSTEM FOR BUILDINGS

Substantiating Design Coefficients and Factors for Coupled Composite Plate Shear Walls-Concrete Filled

Composite Plate Shear Wall-Concrete Filled (C-PSW/CF) is an efficient seismic force-resisting system for buildings and is already addressed by ASCE-7 2016.  Coupled Composite Plate Shear Walls-Concrete Filled (Coupled C-PSW/CF) are more ductile and have more redundancy than non-coupled composite plate shear walls, but ASCE currently does not assign them seismic design coefficients and factors. This FEMA P695 study was conducted to substantiate the design coefficients and factors that should be used for such CC-PSW/CF structures.  

The Charles Pankow Foundation in partnership with the American Institute of Steel Construction is pleased to share this final report of research grant #05-17 conducted by principal investigators:

  • Dr. Michel Bruneau, SUNY Distinguished Professor, University at Buffalo Department of Civil, Structural and Environmental Engineering Buffalo, NY

  • Dr. Amit H. Varma, Karl H. Kettelhut Professor, Purdue University.

ADVANCING WIND DESIGN FOR HIGH-RISE BUILDINGS

New Research Grant:  Systematic Study using Modern Wind Tunnel Test Methods Will Inform Code-based Design 

The Structural Engineering Institute (SEI) of ASCE is pursuing the update and simplification of the 2016 edition of ASCE 7 Minimum Design Loads and Associated Criteria for Buildings and Other Structures approach to wind design. While tweaks have been made over the years, a systematic study using modern wind tunnel test methods for code-based design has not been conducted in over 40 years. Meanwhile, our knowledge of both the role of turbulence on aerodynamic loading and the turbulence levels in the atmospheric boundary layer have evolved considerably. This research will provide test data to the ASCE 7-22 Wind Loads Sub-Committee for review and possible update of chapter 27 MWFRS wind load coefficients.

The Charles Pankow Foundation is pleased to award to the American Society of Civil Engineers Structural Engineering Institute Research Grant #04-19 for Determination of Pressure Coefficients for High-Rise Buildings of Different Aspect Ratios, Principal Investigator Don Scott, P.E., S.E., F.SEI, F.ASCE. Joining the Foundation in support of this research are CPP Wind Engineering & Air Quality Consultants; Degenkolb Engineers; Gilsanz Murray Steficek LLP; Hatfield Group; KPFF; LERA Consulting Structural Engineers; Magnusson Klemencic Associates Foundation; Nabih Youssef Associates Structural Engineers; National Council of Structural Engineers Associations; Odeh Engineers, Inc.; PCS Structural Solutions;  Silman; Skidmore, Owings & Merrill; Structural Focus; Walter P Moore and Associates, Inc.; Peter A. Irwin, Ph.D., P.Eng.; and Glenn and Judy Bell. The research will be guided by the ASCE 7-22 Wind Loads Sub-Committee.

FEMA P695 Study – “Enhanced Ductility” RC Coupled Wall Systems

  • UCLA

  • PI: John W. Wallace, UCLA

  • Co-PI: Kristijan Kolozvari, California State University Fullerton

Click here for more information

The study will examine the application of the FEMA P695 Methodology to ED-RCCW buildings less than 240 ft. in height to determine appropriate values of R, Cd, and Ω0; for buildings greater than 240 ft. tall, ASCE 7 requires a dual system. The study will follow the same general approach as used for the trial studies outlined in NIST (2010) for RC shear wall buildings as summarized by Gogus and Wallace (2015). A single configuration, with two cantilever walls coupled by a single “column” of coupling beams over the building height will be considered to illustrate findings for a range of building heights and design parameters. Important design variables are anticipated to be coupling beam aspect ratio (ln/h) and strength (Vn), and wall cross section geometry, i.e., planar wall versus flanged wall cross section. The expectation is that trial values of R, Cd, and Ω0 will be selected, and the objective of either confirming these values or iterating to refine these values. Iteration may be limited to a subset of the initial study.

  • University of Colorado

  • PI: Professor Keith Molenaar

Revisiting Project Delivery Performance

The goal of this research is to empirically compare the cost, schedule and quality performance of design-bid-build, construction manager at risk and design-build delivery methods. Using the same methodology as employed by Konchar and Sanvido (1998), but with a data set of contemporary projects, the comparison will leverage a mixed-method approach, split into two main phases: (I) prediction of performance through multiple linear regression modeling and (II) assessment of model robustness and validity through case studies.

Announcing a New BIM Tool for Masonry Developed Through the Efforts of the Building Information Modeling for Masonry (BIM-M) Initiative

Announcing a new BIM tool for Masonry developed through the efforts of the Building Information Modeling for Masonry (BIM-M) Initiative. The Charles Pankow Foundation is a Strategic Partner of BIM-M and a co-sponsor of much of the research that supported this new BIM tool.

Masonry iQ is an Autodesk® Revit® plugin that supports masonry products and allows the user to create masonry specific wall types. A wide variety of custom bond patterns can be generated through the user interface which includes a 3D viewer to visualize patterns and bonding at corners. These patterns are analyzed and mapped to walls accounting for proper layout and bonding at corners and openings. Non-modular layouts will be flagged and proper field cuts are represented in elevation. Wall sections are automatically generated showing proper coursing and bond beam locations. Bond beams also generate sweeps for coordination. Three different corner joins (mechanical bond, miter and squared off) are supported and adjusted for proper layout. Single and multi wythe walls are supported. Control Joints and other masonry properties are supported. Material schemas using materials from participating manufacturers allow for rendering of masonry elevations that represent the pattern actual pattern and range indicated.
