Design Solution

IDENTIFYING PROJECT BOUNDARIES AND COMMUNICATING THEM ARE IMPERATIVE TO AN EFFICIENT DESIGN PROCESS


16

Budget

•Restraints are chief concern

•Often primary driver of design execution

Aesthetic

•Meets functional and visual objectives

Technical

•Resist typical cladding loads (wind) and a-typical loads (blast)

Product

•Custom systems impact the cost

• “Off-the-shelf” solutions are desirable

BOUNDARIES:

IDENTIFYING PROJECT BOUNDARIES AND COMMUNICATING THEM ARE IMPERATIVE TO AN EFFICIENT DESIGN PROCESS


17

CAPTURING ACCURATE LOADS IS THE FOUNDATION OF A SUCCESSFUL PROJECT


18

DESIGN KEYS

• ARCYBER Unique Load = Blast

• Intensified Load Capture

• Subject to site-specific threats

• Increased levels of protection

• Highly visible

• Accurate loads reduce cost escalation and risk

• Simplified engineering models

• ConWEP used for base load

• BlastX used for basic geometries

• CFD modeling in complex areas

• Simplify loads into concise specification language

Karagozian and Case’s Threat Evaluation and Consequence (KC-TEC) modeling software used

Used Design Teams Revit model

Modeling include “front” shown and Existing Building Interface (not shown)

Capture load for the new facility

No adverse effects

Accurate loading reduced load over-prediction

KEY FACTS

BALANCING CLIENT EXPECTATIONS AND GOVERNMENT REQUIREMENTS OF PERFORMANCE CAN BE TRICKY


20

Client Expectations

• Mission continuance

• Security of interior assets

• Safety of personnel

• ARCYBER = Safety of personnel

Government Requirements

• DoD, GSA, DoS, etc.

• Protection level or expected performance limit

• ARCYBER:

• DoD Design Criteria – Design for the load and no balanced or plastic capacity based design

• MLOP – Higher than typical DoD facilities (UFC 4-010-01)

• Dynamic design, high end load prediction and custom performance spec

Custom Spec referenced in multiple architectural UFGS specs

Highlights:

Blast design loads

Acceptable Glazing Response – ASTM F2912

System design specifics – Dynamic performance limits, connection design, silicone and bite requirements

Testing – Design alternative or utilize previous vendor work

Custom films – Orientation, IGU interaction concerns, orientation

Submittal requirements – Calculations details and engineer experience level

Mockup requirements and client attenuation testing

Special inspection – Bite, installation orientation, materials

Product or material specifics – Certain glazing components may need to be sole sourced

SPECIFICATION – BLAST RESISTANT GLAZING SYSTEMS


21

Properly vetting concepts

Late-time footprint and floor plan changes can be costly

Overall glazing thickness and mullion depth

Glazing checks – Utilized WinGuard to verify

Mullion checks – Utilized SBEDS to verify

Other important issues:

Long span members

Avoid load bearing primary vertical members

Utilize floor and roof diaphragms

Avoid glazing retention requirement

VETTING DESIGN CONCEPTS

DESIGN SOLUTION


23

Clean design drawings and a robust performance specification allows the client to maximize their budget while meeting their project goals

SECONDARY / INDIRECT CUSTOMERS


27

Upfront research and communication

by design team

• Curtain wall members designed to appropriate depth

• Discussion and consideration to understand product limitations

• Utilization of knowledge learned

Clear Information in the early stages

of the project

• Well written specifications

• Blast performance criteria was clear and thorough

• Intent presented clearly in drawings

WINS FROM MANUFACTURER PERSPECTIVE


28

MAIN CHALLENGE TO DATE HAS BEEN TALL FREE SPAN ELEVATIONS


29

Aluminum Mullion

• Extrusion Length Limits

• Large Custom Extrusions

• Finishing Capability

• Material Handling

Steel Reinforcement

• In-house steel shapes not sufficient

• Stock Steel Shape Availability

• Shipping and Handling - Weight and Length

• Installation

MANUFACTURER CHALLENGES

BLAST DESIGN CHALLENGES


30

Plastic Response

Yield Point or Hinge

Continuous Vertical Mullion Length

• Simply supported beams yield first at mid-point under very high loads

• SDOF (Single Degree of Freedom) analysis assumes a continuous uniform section.

Balancing Limitations and Design

• Making two pieces act like one.

• Splicing Vertical Members.

Doors

Typically resist blast loading about their weaker axis

Deflect beyond performance requirements quickly

Taller pairs of double doors

Substantial Reinforcement

Weight

Hardware Considerations

SECOND MAJOR CHALLENGE – TALL GLAZED DOUBLE DOORS


31

Work closely with manufacturers

early

Understand limitations

Develop open lines of

communication

Provide quick and timely answers

Communication, communication, communication

FUTURE OPPORTUNITIES FOR EVEN GREATER SUCCESS


32 Opportunities exist to better help everyone succeed

• Curtainwall is achievable, even in highly secure environments.

• Coordination between the architect, engineer, and manufacturer is critical.
