• It would be the only half-witted decision of
  general contractors to put profits on priority
  during infrastructure development and civilians
  safety, secondary, against natural calamities
  such as earthquakes, floods, blizzards etc. To
  construct disaster-resilient buildings and
  infrastructure structural engineers, civil
  engineers, steel and rebar detailers keep
  themselves updated with constantly evolving
  earthquake engineering and sciences of seismic
  natural occurrences.

• Researchers have designed fibre-reinforced
  concrete beams, base isolated buildings and what
  not. However, these AEC professionals forget the
  most widely used technology, BIM for Structural
  Engineers, in todays construction practices.

• BIM technology holds all the four aces to turn
  the game of infrastructure development in favour
  of structural and civil engineers.

• By leveraging BIM technology, proportionately,
  structural engineers can reach the zenith of
  building and infrastructure development. BIM
  along with a finessed 3D model of infrastructure
  and/or custom API programming have the capability
  to conduct fortification analysis and seismic
  analysis of the structure. Seismic retrofitting,
  design coordination and building codes are some
  of the sectors where BIM plays protagonist with
  its imperative virtual design and construction
  tools.

• With continuous population explosion, the lateral
  expansion of buildings has in fact shifted to
  vertical rise. Skyscrapers and high-rises have
  become an increasing necessity of urban
  infrastructure development along with flyovers,
  bridges and underground tubes.
• Building Information Modeling incorporates early
  seismic needs, to eliminate design modification
  once the construction starts. Information rich
  intelligent BIM ready 3D models of infrastructure
  designs are critical when complying with the
  seismic specification.

Compliance to designs and building codes in BIM
environment minimizes seismic effect damages
6

• Regulations call for a two-inch space between
  ducts to prevent damages in the earthquake and
  its inclusion in 3D models is an example of how
  neatly BIM ensures correctness of designs and
  compliance to codes.
• Fundamentally, with BIM, any hanger, brace etc.
  can be modelled designs of sleeves, decks,
  roofs, beams, columns etc. can also be validated
  using BIM. Alongside, by developing more custom
  plugins and tools that offer access to their
  APIs, tasks are automated and code compliance
  checking is streamlined.

Retrofitting of Earthquake Affected Infrastructure
8

• BIM not only aids structural engineers while
  working on the preparation of designs from
  scratch but also ensures that structure is
  revamped as it was before the earthquake. Having
  said this, BIM plays a significant role while
  working on retrofitting of earthquake affected
  infrastructure and buildings. It captures the
  reality of the as built condition of any
  structure with help of point cloud information
  and converting it to 3D BIM models or
  photogrammetry.
• It is impressive to see how AEC professionals are
  using unmanned aerial vehicles (UAV) and a
  high-resolution camera to get exact as-built
  conditions of roads, bridges, and tunnels. Upon
  modelling and analysis of this captured
  information in BIM structural software such as
  Autodesk Revit Structure, it shows the
  displacement under seismic load when virtually
  simulated.

• However, while retrofitting, just knowing the
  particle displacement of structure material is
  not enough. Other challenge lies in meeting the
  supply and demand of material as envisioned for
  retrofitting project. The other challenge lies in
  how to coordinate all the energy in a
  choreographed construction methodology that
  ensures timely completion and fall within
  financial budgets in earthquake affected
  geography. BIM plays a pivotal role in
  programming and sequencing all construction
  activity, aligning materials on sites and
  optimizing supply and delivery. BIM thus removes
  inefficiencies and inaccuracies that are caused
  due to the piecemeal ordering of materials.
• BIM was initially meant to upgrade fundamental
  ways in which designing was done and bring
  efficiency to the overall construction process.
  But with the gradual advent of technology, BIM
  now serves Construction Management processes as
  well. Also when stakeholders and the public can
  see proposed building designs in form of 3D
  models and can walk through a virtual prototype
  of intended infrastructure piece, decisions can
  be streamlined and retrofit earthquake affected
  infrastructure can be accelerated.

Fiber and Steel Columns and Base Isolation
Methods for Sustaining Seismic Vibration
11

• These beams, when reinforced with concrete and
  steel fiber, can sustain seismic loads at higher
  levels. Such innovations find applications in
  bridges, flyover, and high-rise construction.
  Besides, there are several other popular
  facilities constructed, such as Taipei 101 in
  China, that are built on the separate foundation
  which acts as a shock absorber. It essentially
  allows the building to stay stationary relative
  to the ground even during seismic vibrations.
• Adopting such modern approaches based on a static
  nonlinear algorithm, also known as dynamic
  analysis give the more exact representation of
  buildings when simulated for seismic conditions.
  This pushover analysis delivers erecting a
  stronger foundation for high-risk construction.
  Using BIM is a cost-effective solution for
  infrastructure project development and it is
  unarguable. As the industry enters the next
  decade, it will have the ability to perform with
  a single BIM model. BIM itself will soon become
  the new normal for structural engineers to deal
  with earthquake engineering as well.
