As the population rapidly increases and rural and urban migration has continued at a faster rate, demands for residential and commercial property are growing. This continual growth in population and demand for workplaces and housing has pushed developers and builders to build vertically. On a rarely seen occurrence, reserved primarily for the urban areas, high-rise buildings have become a common site in mini-metros and cities.
The growth of vertical building structures has led to faster development of innovative techs and methods to successfully achieve a much safer and aesthetically pleasing structure at a faster rate. Speaking of innovative techs, there’s many to mention, including concrete systems, support systems, facades, and even
KONE UltraRope is the new carbon-fiber hoisting technology, the heaviness and bending benefits of which effectively double the distance of the elevator in traveling within a single shaft (1km). KONE is comprised of epoxy-based high friction coating and carbon fiber core. It is extremely light, causing machine room size and elevator energy consumption in high-rise buildings can be significantly cut.
The drop in rope weight solely means a significant reduction in elevator moving masses. The latter refers to the weight of everything that typically moves when the elevator travels up and down, including the compensating ropes, hoisting ropes, elevator car, counterweight, and passenger load.
Currently, elevators are pretty limited to a single-shaft height of five hundred meters, the point where the thickness and mass of steel rope can make height further impractical. But with UltraRope, the elevators in high-rise buildings can travel up to one thousand meters without the need for transfer lobbies.
2. MEGA TRUSS Seismic Isolation Structure
The designers of the multipurpose high-rise were able to solve two distinctive requirements in one building with the use of an integrated structural solution that can transfer force safely through the transition. One part of this program is a concert hall built out from reinforced concrete walls in order to form a rigid frame, acoustic performance and sound isolation. Right above, the program called for modern offices, which are preferably column-free for maximum flexibility.
The intermediate seismic isolation, selectively comprised of a Mega Truss with mega columns, diagonals, a belt truss, oil dampers, lead rubber bearings, enables these contrasting requirements to coexist in the same building.
This innovative structural system has significantly allowed builders and designers to develop a seismically tall isolated building. MEGATRUSS truly deserves recognition due to its capability to transfer systems and integrate base isolation into remote systems in a higher seismic area.
3. RASTER Façade Precast Concrete System
The Raster Façade is known as a load-bearing precast concrete frame. It can remove interior columns in tall buildings, allowing the floor to ceiling glasses by way of triple-glazing with external retractable protective louvers. It can also generate more usable floor area compared to other systems.
This precast façade can generate a ratio of sixty percent glazed to forty percent closed surfaces, enhancing insulation values. In fact, heating and cooling systems are often incorporated into suspended ceiling panels, which is found to be more efficient than putting or installing such systems on the floor.
Moreover, precast concrete is an integrally fireproof building material, eradicating the need for additional fire protection. This particular innovation only shows that load-bearing precast concrete can be an excellent option to the glass curtain walls generally intended for high-rise building construction.
High-rise building construction is one of the dangerous, if not toughest, jobs to do. Looking out for crew members is exceptionally crucial. And while providing the best PPE and safety tools for your construction team is the very first thing you do, you may consider deploying a subcontractor scheduling software for overall tracking and monitoring of your employees.
4. ROCKER Façade Support System
The Poly Corporation Headquarters now features a unique design component purposely created for high-rise buildings – The Rocker. The Rocker Façade can support even the biggest cable-net glass wall while actively releasing the immediate effects of heavy winds and earthquakes. Moreover, it also facilitates the suspension of an 80-story, lantern-looking museum structure in an office building’s atrium.
Structural analysis has shown that the support system for a twenty-two-story tall glass atrium wall cannot be reasonably accomplished using a conventional two-wat cable net. Instead, it can be achieved if a ninety-meter high by sixty-five meter wide enclose is broken down into small segments. This is where a cable-stayed system was being introduced by utilizing two large-diameter parallel bridge cables while anchoring to the eight stories lantern-like museum structure.
This particular innovation can be adapted for use in other circumstances that may be encountered in unique tall buildings, where construction workers may need to get free from participation in the crosswise systems of the structures. Safety for construction workers is a top priority. And alongside these innovations for high-rise, business owners and contractors have to also invest in other advanced technologies, like construction scheduling software for scheduling and tracking purposes.
5. BSB Prefabricated Construction Process
The Broad Sustainable Building (BSB) captured the industry’s attention when the broad group has developed and constructed T30 – a thirty-story building built in fifteen days in Changsa, China, using only pre-assembled components.
The process utilizes a factory-fabricated steel structure system. And during on-site installation, high-strength bolts and flanges are used to help construction members. It also incorporates installable and integrated floor slabs, wallboards, and other prefabricated materials.
Such a process can give enormous advantages to buildings. It can provide a magnitude-9 earthquake resistance five times the energy efficiency of a traditionally constructed structure, with ten to thirty percent lower cost. BSB construction process is proven produced less than one percent of the waste compared to traditional or usual site-built construction.
