Design Principles for Earthquake-Resistant High-Rise Buildings

#Hacker40 | 2021: Revitalizing a Brutalist public library into a humane 21st Century community hub In 2017, Salem's residents voted in favor of preserving their massive concrete public library and modernizing it for 21st-century needs. Structures from this era are reaching a point where revitalization is essential, yet communities often find themselves constrained by budgets that primarily cover earthquake safety, the replacement of outdated equipment, and repairs to address issues like leaky roofs and windows. The transformation was focused on areas that significantly shape the public experience and enhance the library's functionality for staff, ensuring the library's cherished status for another 75 years. Despite working within tight financial constraints, every dollar was meticulously allocated, with a primary focus on introducing natural light into the heart of the once fortress-like structure. The outcome is a bright, open space that now warmly welcomes the community, effectively turning the inward-facing, brutalist-era building into a vibrant hub nearly half a century after its initial opening.

Looking for solutions to deflection and vibration concerns for floors in your open floor plan buildings? 🏗️ In the recent issue of Canadian Society for Civil Engineering / La Société canadienne de génie civil's CIVIL magazine Tyler Hull and Daniel Lacroix discuss a solution to this problem in the form of Mass Timber Composite (MTC) panels. By compositely connecting the CLT panels and glulam beams, MTC panels have increased capacity and stiffness. Discussed in the article are implications for designers to consider and the current research our team is conducting at the University of Waterloo. This work comes from a collaboration with Element5 and their hollow core BOXX panels, which are floor and roof cassettes that offer a material efficient way to achieve long clear spans in multi-storey buildings. If you are looking to use these on your next project reach out to us and the team at Element5 for help with your design. 📞 See the full publication here 📃https://lnkd.in/gSjARCNe #masstimber #structuralengineering #research #sustainability #engineering #CLT

An impressive video highlights the construction of a bridge using the incremental launching method!! Incremental launching is a special construction method of building a bridge to overcome access problems or minimize disruption at ground level. Incremental launched prestressed concrete bridges are built in segments in a casting bed and the finished segments are pushed out of the casting bed to leave space for the construction of subsequent segments. Special knowledge and a high degree of temporary works integration are required in order to successfully design an incremental launch bridge. Most of the superstructure construction activities are carried out at the casting bed area. Bridge barriers, bridge lightings, and drainages can be installed prior to launching.   This technique is generally used for bridges spanning less than 60 meters and require a high degree of technology for both design and construction, and hence demand sophisticated structural analysis and design techniques when compared with other conventional bridges. There are two distinct stages to analyze, the launching stage and the in-service stage. Furthermore, there are also two distinctive groups of pre-stress to accommodate the actions from each of these stages.

Ever wondered what keeps iconic bridges standing strong for more than a century? It's no magic trick—it’s the result of advanced geotechnical and civil engineering practices. The longevity of a bridge starts with its foundation. Geotechnical engineers play a crucial role in assessing the ground conditions and ensuring a stable base. Techniques like deep foundation systems, pile driving, and soil stabilization are key to making sure these massive structures stand firm, even in challenging environments. But it's not just about what's below ground. Above the surface, the use of innovative materials and smart design principles adds to the durability. High-performance concrete, weather-resistant steel, and modern composite materials help bridges withstand the elements and heavy usage over time. Take the Golden Gate Bridge, for example. This iconic structure has been standing tall since 1937, thanks to its robust engineering design and regular maintenance. Innovations like corrosion-resistant paint and seismic retrofitting have been crucial in extending its lifespan. Then there’s the Brooklyn Bridge, which opened in 1883 and still carries thousands of vehicles and pedestrians daily. Its enduring strength is due to the meticulous work of engineers who used revolutionary techniques for their time, like caissons for underwater foundation work. Regular inspections and proactive repairs are also a big part of the equation. Ongoing maintenance ensures that any potential issues are spotted and addressed before they become major problems. In essence, the secret to a bridge lasting over a hundred years lies in a combination of solid foundations, advanced materials, innovative design, and continuous upkeep. It’s a testament to the power of engineering and the relentless pursuit of excellence. Next time you drive over a historic bridge, take a moment to appreciate the incredible engineering that keeps it standing strong. #EngineeringMarvels #GeotechnicalEngineering #CivilEngineering #BridgeDesign #InfrastructureInnovation

One of Element5's Core Values is to strive to invent and re-invent how mass timber manufacturing is done. through ongoing innovation. To help us achieve this goal - we partner with other organizations, companies and institutions to advance our knowledge and understanding of mass timber. A good example of one of these partnerships is with the START - Structural Timber and Applied Research Team at the University of Waterloo. They just released some of their findings on using mass timber composite panels to meet the challenge of using mass timber for open floor plan structures with long floor spans and still meet vibration performance standards.

As a structural engineer, what do you think about the design of this building? What is the effect of this solution on earthquake resistance? PARADOX TOWER, one of the tallest and unique residential buildings in Mexico designed by VARABYEU PARTNERS. An extremely complex aspect of this project is its irregularity in plan and height, which causes instantaneous lateral displacements of up to 15cm on the roof due to the effects of its own weight and permanent loads. To minimize these construction movements, a complex step-by-step structural analysis is adopted with a construction “in reverse” of the expected displacements on each floor, which materializes with displacements imposed between the base and the head of each column of each floor between 10 and 20mm. Compensating the geometry of each level, it is built counteracting the deformation and keeping the elevator core straight without practically any collapse. The horizontal calculation movements were very precisely correlated with measurements throughout the construction process. The structure is made up of a central concrete core and on one side SLBs on metallic diagonals together with spatial frames on the perimeter of each tower and interior flat space to facilitate installations and make better use of space. The foundation is based on 150cm diameter piles and a central foundation slab. Therefore, the “resistant skeleton” is formed by frames only on the perimeter of each building A, B and C, but without hanging beams inside the building. Inside, and only to reduce the span to approximately 12m, there is one column per building that does not contribute to the lateral load system (they are only available by gravity).

Irregularities in Structures and Earthquake resistant design.... A big gap in understanding, especially amongst Indian Architects and Clients (and most of our Structural Engineer friends too) Honestly guys and girls, how many of us have tried to understand the implications of the very elaborate guidelines on Irregularities in structural configuration, as laid down in BIS 1893 part-I, or dared to point that out to a High and Mighty Architect selling glamorous building elevations and plans .... Our BIS Codes (and our own understanding of the subject) clearly recommend regular building geometries in cities vulnerable to earthquakes. In addition, a regular closed geometry in plan is the most economical one, structurally vis a vis a flower shaped one with a central core connecting say six or eight or four petals (read Flats). Equally Interesting and relevant are the BIS 16700 stipulations on building length to width ratio; height to width ratio, and the structural configurations not permitted in Zone IV and V; Glaring example being the good old beam column system, also known as a Moment Frame, no longer an option in Zone IV and V without providing well designed RCC Shear Walls......now these guidelines are completely lost sight of, while planning is carried out, for Building Plans, elevations et al and the poor structural engineer ends up answering for high steel ratios,which are a direct result of highly irregular configurations, stub columns, very large spans and large cantilevers, Flat slabs etc(which logically a complete NO in high seismic zones) Not to forget NDMA Hospital Safety Guidelines(a Free downloadable document in NDMA website) I believe most of even my structural engineer friends have never gone through it's chapter 5 on Structural design mandate, prohibiting Irregular structures, Flat Slabs, Precast Slabs, PEB buildings and so on, for Hospitals in Zones III,IV and V.Fortunately enough, most of these will now get added to the revised BIS 1893 when it shows up early this year. and Last but not the least, BIS 1893 part-I will come now in a new Avtar, backed with a Part-II for buildings, carrying a Seismic Zone VI and many cities will see a change over to higher zones with higher coefficient Z. The Big question is, are we prepared to handle the Change?
