A correction to the following paper: F. Zhang and M. Rosenfeld Longitudinal stress in buried pipelines near bends or end caps Journal of Pipeline Engineering, 2nd Quarter, June 2018, pp. 73-89. Page 79, 1st sentence of under “Results Comparison” [correct values are in bold] “Based on the pipe dimensions, buried depth, and soil properties listed in Table 1 and Table 2, we determined the soil stiffness in the lateral direction and axial direction as 𝑘 = 𝟑𝟕𝟎. 𝟐 lbs/in2 and 𝑘𝑎 = 𝟕𝟒𝟏. 𝟕 lbs/in2, respectively, …” The incorrect values for 𝑘 and 𝑘a as shown in the paper were carried over from an older draft. The authors apologize for not recognizing the error during proof reading before publication. The figures in the paper were based on calculation with the corrected values and thus the typos do not influence other parts or the conclusion of the paper.

Recently, I’ve received several questions regarding the production rates of microtunneling projects. So, I wanted to take this opportunity to highlight some key insights from my paper titled "Modeling Microtunnel Boring Machine Penetration Rate Using a Mechanistic Approach," which was published in 2022. In this paper, I introduce an advanced analytical and mechanistic approach to model the penetration rate of microtunnel boring machines, considering key factors such as: 1) Operational loads, 2) Soil types and ground conditions, and 3) Cutterhead shape and configuration. This work delves into the excavation mechanisms of microtunnel boring machines, offering valuable insights into how these factors influence penetration rates. It has been a deeply rewarding journey, and I’m grateful for the support I’ve received along the way.

Presentation Recap: Dynamics of Fire-Induced Concrete Spalling 🔥🏗️ Last week, I presented my research on "UNRAVELLING THE DYNAMICS OF FIRE-INDUCED CONCRETE SPALLING: A FOCUS ON THERMAL ENERGY IN A TWO-STAGE MECHANISM." This study introduces a new framework to understand the violent expulsion of concrete fragments during fires, emphasizing a two-stage mechanism involving crack formation and rapid propagation. Grateful for the engaging discussions and feedback!

This is an insightful work by Deepali Anand Exploring the Effects of Climate Change on Ground Deformation: This study delves into frost heave and thaw settlement in permafrost regions, crucial for engineering safe structures. Through finite element modelling, it analyzes how sequential layering affects varved clay profiles' mechanical behavior under temperature fluctuations. Lab-tested parameters and thermal properties inform interesting findings. Varied deformation levels and layering impacts underscore the study's significance in designing resilient structures. #ClimateChange #Engineering #Permafrost"

I’m excited to share a new paper resulting from a collaboration between Universidade Presbiteriana Mackenzie, Universidade Tecnológica Federal do Paraná, Centro Universitário Estácio de São Paulo, and Universidade de São Paulo. A big thank you to all the co-authors! This study builds on our previous research involving Ultra-High Performance Concrete (UHPC). In this paper, we focus on quantifying the internal damping properties of both ordinary and high-strength concretes. We analyze these properties for intact samples and assess how damping evolves as damage increases.
