Temple Bracing Standardization

Senior Design Project


Introduction

Introduction

  • 140 LDS temples currently in operation, 12 under construction and 16 announced

  • Temples need to be built and maintained with the latest advancements in seismic design

  • Mechanical systems integrated into temples need to be designed for seismic loads

  • This project addresses the need for specifications (specs) and details for the seismic restraints of mechanical systems in LDS temples


Project organization

Project Organization


Design problem

Design Problem

  • Mechanical systems are often designed for gravity loads with seismic loads neglected

  • Mechanical systems in past temples are vulnerable to seismic loads

  • Seismic bracing expected but often inadequate quality control and accountability

  • Standardize mechanical system seismic bracing utilized in LDS temples

  • Create details and specs, in accordance with design codes, to be used by design engineers


Process

Process

  • Understand the customers needs and expectations

    • Determine Deliverables

  • Fully research seismic design codes and guidelines (ASCE 7-10.13, SMACNA, ASHRAE)

  • Learn from industry professionals.

  • Refine project schedule and set measurable goals and deadlines

  • Hold each other accountable


Deliverables

Deliverables

  • Seismic bracing of ductwork details drawn in Revit

    • Brace spacing guidelines


Deliverables1

Deliverables

  • Seismic bracing of ductwork details drawn in Revit

    • Rectangular and round ductwork bracing

Longitudinal

Transverse

Rod Stiffener


Deliverables2

Deliverables

  • A guideline with clearly defined seismic design expectations, ensuring installation of proper seismic bracing

    • Based on ASCE 7-13, SMACNA, ASHRAE, advice from industry professionals


Learning outcomes

Learning Outcomes

  • Understanding and managing customer expectations is the essence of any project

  • Differences in a team should be welcomed and harnessed

  • Accountability is essential for progress

  • Obtaining advice from industry professionals was vital to our success

SEISMIC BRACING OF LDS TEMPLES

The Church of Jesus Christ of Latter-day Saints builds and maintains beautiful temples of worship throughout the world. It is expected that the life of these temples will span many generations as places to serve and worship God. In order for temples to remain functioning and operational, they need to be built and maintained with the latest advancements in seismic design. In addition to the structure of the temples, there are many mechanical systems integrated into the operability of the temple. These mechanical systems need to be designed for seismic loads. This project addresses the need for specifications and details for the seismic restraints of the mechanical systems within LDS temples.

Brace Spacing-

Specifications-

Details-

Seismic bracing of HVAC systems must be spaced at specific intervals to ensure performance during a seismic event. The Brace Spacing Steps provided help the engineer easily determine the spacing of seismic braces.

Recommended specifications were also provided. These specifications will ensure all bids from engineers and contractors will be consistent and comparableand ensure proper seismic bracing of non-structural components. The specifications include clarification on items in ASCE 7-10 Chapter 13, definitions, submittal, force design, bracing and connection requirements.

Details were provided for various situations, including Rectangular Duct Transverse Bracing, Round Duct Transverse Bracing, Rectangular/Round Duct Longitudinal Bracing, Equipment Bracing and Rod Stiffening. Drawing examples are shown below.
