                                  6- Practical Consideration.

Damage Control In Building:                           

Damage control for columns in structures, particularly during seismic events, focuses on mitigating damage to main structural members by strategically placing or designing components that can absorb and dissipate energy, allowing the primary structural elements to remain largely intact. This can be achieved through various techniques, including replaceable fuses, steel shear links, and confinement measures.  

Replacement of damaged concrete members:

The replacement of damaged concrete elements requires demolition and removal of existing structural elements and their substitution with new members. The demolition process is carried out after proper jacking is applied to relieve imposed loads on the damaged structural member.

Great care should be practised to avoid damaging existing steel bars if present. This measure is considered to splice the existing bars with the newer ones.

A complete replacement of structural member is considered for structural members that have been damaged severely, and it would be the most cost-effective method or an economic choice for the repair of the member. The replacement method has been widely used to repair structures that suffered from earthquakes.

The newly constructed structural member should possess similar strength to that of the previous element or improve to a certain extent. All damaged concrete structural members such as beam, columns, braces and walls can be replaced.

When is Damaged Concrete Members Replacement Required?

This repair method can be used if none of the other strengthening techniques is adequate. Not only is this technique used to repair deteriorated buildings but also employed to increase life span of structures specifically bridge structure. This method is specifically suitable for strengthen buildings that are hit by earthquakes. 

Specification of Repair Materials:

Repair materials should be specified based on the specifications and recommendations of applicable codes. For instance, for reinforced masonry walls, open-ended masonry units should be employed, and masonry units, grouts, and mortar used need to meet requirements of ACI530/ASCE 6. For reinforced concrete member, the minimum concrete compressive strength is 21MPa.

Replacement Execution:

1. If the damaged structural member is load-bearing, shoring needs to be provided adjacent to it to withstand loads while the member is demolished and not present to carry the loads.
2. The structural member must be carefully demolished using proper tools such as saws and chipping tools.
3. If present, steel bars should not be damaged in order to splice them with new steel reinforcements which are going to be installed for the new structural member
4. The surface of the surrounding structure should be prepared to make sure adequate bond is generated between existing and new materials, for example, roughening surfaces.
5. New reinforcing bars should be spliced to existing bars.
6. If new reinforcing bars are required to be attached to the existing structure, these bars should be anchored to the existing structure by setting them into holes with epoxy.
7. The depth of the holes needs to be adequate in order to make sure that the full potential of the steel bars is utilized. It is advised to consulate epoxy manufacturer for the proper depth of the bar and for the instructions for installing the epoxy.
8. The new concrete can be poured using suitable means. For example, using formworks  or applying shotcrete.
9. If formworks are employed, fresh concrete is poured through an access hole near the top of the formwork, and extra holes may be required to provide access for vibrators to consolidate concrete.
10. Finally, proper curing regime is used to make sure that concrete achieves the designated strength.

Practical Consideration:

Due to the fact that newly placed concrete would inevitably experience shrinkage and existing concrete would not undergo any movement, the concrete of new constructed member would develop cracks.

These cracks need to be repaired after significant amount of shrinkage has occurred for instance after two to four months. The shrinkage cracks should be repaired using epoxy or any other suitable repair materials.

A percentage of the epoxy-anchored dowels should be load-tested to at least 50 percent of the yield strength of the bar. A special inspector familiar with epoxy installation should observe installation of the epoxy.

Finally, the layout and anchorage of the reinforcing steel should be inspected before forming the concrete.

  • Aesthetics: Kinetic elements can add visual interest and dynamism to a building's design. 
  • Functionality: Kinetic elements can create new spaces or allow for different uses of a building. 

  
  

  Examples of Kinetic Architecture:
• The Burke Brise soleil (Milwaukee Art Museum): A kinetic structure that protects the museum from the sun and rain. 
• Drawbridges: A classic example of a kinetic structure that allows for the passage of ships. 

FAQs

1. How reliable are the mechanical systems in kinetic buildings?

Modern kinetic structures are incredibly reliable, with redundant systems and predictive maintenance. For example, the Burke Brise Soleil at the Milwaukee Art Museum has completed over 78,000 opening and closing cycles with a 99.7% reliability rate, even under extreme weather conditions. Advanced designs feature self-diagnosing systems that detect issues before they become problems.

2. What happens if the power fails?

Kinetic buildings often include backup systems. For example, the rotating floors in Dubai’s Dynamic Tower are equipped with self-contained energy generation. Many other designs include manual override capabilities or fail-safe positions. Some systems are so finely calibrated that they can be operated manually with minimal force during emergencies.

3. Are kinetic buildings earthquake-resistant?

Yes! Some kinetic designs actually offer superior seismic performance. The Earthquake House in Japan features a kinetic base isolation system that actively counteracts seismic forces by redistributing them through controlled movement. This strategy, inspired by how trees sway in storms, allows the structure to absorb and adapt to ground movement rather than resisting it.

4. What’s the most innovative kinetic structure currently in operation?

The Media-ICT Building (Barcelona) stands out with its remarkable ETFE façade, which inflates and deflates in response to solar conditions. This "digital skin" adjusts its transparency, insulation, and appearance throughout the day. During peak summer, it reduces solar gain by 85%, while in winter, it allows for full transparency.

5. Can kinetic elements be added to conventional buildings?

Yes! One of the most exciting developments in the field is the retrofitting of conventional buildings with kinetic systems. The Kiefer Technic Showroom, for example, transformed a standard office building with 112 motorized aluminum panels, creating an infinitely reconfigurable façade while reducing energy consumption by 40%. These "kinetic retrofits" often provide a return on investment (ROI) in 5–7 years through energy savings alone.

These sophisticated systems employ multiple integrated technologies:

• Deploying distributed sensor networks throughout structures
• Processing continuous data streams using edge computing
• Implementing machine learning algorithms for pattern recognition
• Comparing real-time data against digital twin models
• Generating prioritized maintenance schedules based on risk analysis

Frequently Asked Questions?

How accurate are these AI predictions?

The latest systems demonstrate remarkable accuracy. For example, a bridge monitoring system in the Netherlands correctly predicted stress fractures in a critical support member 4.5 months before they became visible during routine inspection, with a 92% confidence interval. This precision results from algorithms that detect microscopic changes in vibration patterns and load responses.

What's the ROI for implementing these systems?
While upfront costs range from $50,000 to several million, depending on structure size and complexity, the payback period typically falls between 14–36 months. One case study from Singapore showed a 410% ROI over five years for a high-rise building implementation, primarily through prevented emergency repairs and extended component lifespans.

Can AI predictive maintenance work on older structures without digital designs?
Absolutely! Modern systems can create detailed digital twins of existing structures through laser scanning and sensor data. A 120-year-old railway bridge in the UK was retrofitted with AI monitoring that successfully mapped stress points never documented in the original designs, identifying critical maintenance needs that had gone undetected for decades.

How do these systems handle environmental variables?
That’s where AI truly shines. Advanced algorithms distinguish between normal environmental responses (such as thermal expansion or wind loading) and actual structural concerns. Some systems even incorporate weather forecasting data to adjust baseline expectations for structural behavior during extreme conditions.

What happens if sensors fail or communications are disrupted?
Modern implementations include redundant sensor networks and sophisticated fault detection. The most advanced systems employ self-diagnosing capabilities that identify sensor drift or failure, automatically adjust for missing data points, and maintain prediction accuracy even with partial system functionality.
