[NEW PAPER] “Generalised Storey Loss Functions for Seismic Loss Assessment of Italian Residential Buildings” has been published on Journal of Earthquake Engineering (https://lnkd.in/dbvkXuaE) With a view to providing general Storey Loss Functions (SLFs) for existing reinforced concrete (RC) residential buildings in Italy, this paper layouts the procedure and the development of SLFs for different residential building typologies, using post-earthquake observational damage data of the 2009 L’Aquila earthquake. The outcomes denote how the proposed SLFs can be a useful tool as an alternative to the simplified conservative loss assessment guidelines (Sismabonus) currently employed in Italy, with a view to planning risk mitigation measurements both at a regional and single-building level.

Seismic design in Australia: Are you complying with the National Construction Code and Earthquake Standard? Earthquakes with a magnitude of 5.0 or higher, such as the 1989 earthquake in Newcastle, which resulted in the tragic deaths of 13 people and saw more than 160 people injured, occur every one to two years. Considering the potential risks associated with seismic activity, all buildings need an assessment of their seismic design requirements. https://lnkd.in/gkP4haMX

Sustainable Vertical Earthquake Strengthening - Kürberg, Zürich (CH) Project: The Kürberg housing complex consists of a continuous underground parking garage and three apartment buildings. The structural analysis showed that the earthquake resistance was insufficient. Solution: The masonry walls were strengthened with post-tensioned CFRP plates (CarboStress®) to restore earthquake resistance. The plates cover the full height of the building and are anchored in the basement garage deck slab. The fixed end anchors are located on the roofs of the buildings. The post-tensioning force is introduced into the deck slab via a steel component. The tensioned end is in the underground parking garage. 20 CarboStress® systems were applied for the three buildings Would you like additional information?

Shake-table test of a six-story hybrid mass timber structure with a well-designed braced frame (as an alternative to post-tensioned rocking walls) It's a 400% scaled-up simulation of the Loma Prieta earthquake, representing the building code's Maximum Considered Earthquake (USA). The Loma Prieta earthquake was a major earthquake that struck the San Francisco Bay Area of California in 1989. Caused by a slip along the San Andreas Fault, the quake lasted 10–15 seconds and measured 6.9 on the Richter Scale. Adequate building codes and earthquake design technology differentiate between a city left rubble or not. - Credit: Simpson Strong-Tie https://buff.ly/43GutZf

Soil Liquefaction: The Hidden Danger Beneath Our Feet During Earthquakes When the earth shakes during an earthquake, there's a menacing phenomenon that can amplify its destruction: Soil Liquefaction. But what exactly is it? In simple terms, soil liquefaction occurs when saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress such as shaking during an earthquake, causing it to behave like a liquid. Imagine building on solid ground, and in a few terrifying moments, that solid ground turns to quicksand. Why does this happen? The intense shaking from seismic activity can increase the pressure between the particles in wet and loose soils, leading them to separate and cause the soil to flow like water. The implications of soil liquefaction are significant: Building Collapse: Structures can sink or tilt as their foundations are no longer supported by solid ground. Ground Ruptures: The surface can crack and deform. Landslides: Sloped areas can fail and move downhill. Infrastructure Damage: Roads, bridges, pipelines, and other essential structures can be severely affected. Recognizing and understanding soil liquefaction is crucial for architects, engineers, and urban planners, especially in earthquake-prone regions. By identifying areas at risk and using specialized construction techniques, we can mitigate these threats and create safer communities. 🎥 Sun Arts (YT) Channel 10 (YT) 🌎 Do you like it?

We can actually trace some soil problems to soil liquefaction. Note, the external factor triggering the saturated soil to behave like a liquid doesn't really have to be earthquake. They can be mechanical triggers under human influence, volcanic eruptions, etc. It is better to avoid liquefied land areas but if they are not avoidable one of the following prevention method has to be implemented; -Vibro compaaction method - Dynamic compaction - Drainage columns - Grouting compaction. I find this video insightful Watch the demonstration/Illustrations. #geotechnicalengineering #soilmechanics #engineeringsolutions

🌏 Understanding Essence in Process of Earthquake Resistant Design for New & Existing Buildings 🏢 🏢 Buildings sway in all directions during earthquakes, influenced by their size and stiffness. Strong shaking can cause damage, and earthquake-resistant design aims to control and understand this damage. Through detailed analysis and design adjustments, we can enhance a building's ability to withstand earthquakes. 💪🏻 The challenge lies in predicting and managing inelastic actions during seismic events, which are different from other types of loads like wind or snow. ↔️ The connection between analysis, design, and behavior shapes a building's seismic performance, and understanding these relationships is crucial for earthquake-resistant design. ● New Buildings 🆕️ For design & construction of new earthquake-resistant buildings, the process involves three steps: 1. Analyzing the building to understand its seismic behavior; 2. Designing it based on the analysis to ensure it meets seismic requirements, and finally, 3. Observing the building during in next earthquake to validate the design or identify any shortcomings. ● Existing Buildings 🏚 In evaluating the earthquake resistance of existing buildings before an earthquake, the safety assessment follows distinct steps: 1. Analyzing the building to consider all conceivable seismic behaviors using simulated or recorded earthquake motions; 2. Retrofitting each member to align with the desired behavior identified in the analysis; 3. Observing the building during the next earthquake to validate the retrofit design or identify any shortcomings.

Important points for Earthquake resistant Building. It is not possible to predict the exact timing of an earthquake but by taking precautionary measures one could definitely help in minimizing the damage to property and loss of life. During an earthquake most buildings collapse resulting in a high death rate. Here are a few measures that a homeowner should take to prevent damage to property. If building plans include masonry infill walls, the best solution is to add steel frames to correct structural problems. Another solution could be to leave space between the walls and the building frame allowing for some drift as the building moves during an earthquake. To make a building earthquake proof, it is important to put shear walls, a shear core and cross-bracing as they provide additional strength. The building is bolted to the foundation, providing support walls called shear walls, which help in reinforcing the building that in turn resist rocking movements. Shear walls at the center of a building, around an elevator shaft or stairwell form a shear core. In cross-bracing technique, the walls are reinforced with diagonal steel beams. #Structuraldesign #Civilengineering #Earthquake_resistant #Seismic_resilience #Building_design #MPBirlacement #Technical_Support_Services

After the earthquakes: Experts discuss building codes in Türkiye and the U.S. As a result of the two major earthquakes that struck Türkiye in Feb. of 2023, an estimated 320,000 buildings were heavily damaged or collapsed. In northwestern Syria, which was also affected by the earthquake, more than 9,100 buildings collapsed. This earthquake sequence was the most devastating to hit Türkiye in more than 20 years and the fifth-deadliest earthquake of the 21st century. In Temblor's latest, our Simpson Strong-Tie fellow talked to Mustafa Özder Erdik, Professor of Civil Engineering at Bogazici University and Evan Reis, Executive Director and co-founder of the US Resiliency Council about what factors led to so many building collapses, ways to avoid that fate in the future and what California in particular can learn. https://lnkd.in/gD4fRyRn
