The selection and scaling of ground motion records is considered a primary and essential task in performing structural analysis and design. Conventional methods involve using ground motion models and a conditional spectrum to select ground motion records based on the target spectrum. This research demonstrates the influence of adopting different weighted factors for various period ranges during matching selected ground motions with the target hazard spectrum. The event data from the Next Generation Attenuation West 2 (NGA-West 2) database is used as the basis for ground motion selection, and hazard de-aggregation is conducted to estimate the event parameters of interest, which are then used to construct the target intensity measure (IM). The target IMs are then used to select ground motion records with different weighted vector-valued objective functions. The weights are altered to account for the relative importance of IM in accordance with the structural analysis application of steel moment resisting frame (sMRF) buildings. Instead of an ordinary objective function for the matching spectrum, a novel model is introduced and compared with the conventional cost function. The results indicate that when applying the new cost function for ground motion selection, it places higher demands on structures compared to the conventional cost function. Moreover, submitting more weights to the first-mode period of structures increases engineering demand parameters. Findings demonstrate that weight factors allocated to different period ranges can successfully account for period elongation and higher mode effects.

This study explored the thermo-chemical properties of industrial hemp hurd with different provenances, maturity stages, and retting protocols. The findings were then compared to hemp hurd used in the fabrication of citric acid-bonded ultra-low-density hemp hurd particleboard. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/Ms), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA) were employed to document the variability of the hurd and comprehend the potential impact on biobased composite applications. The choice of cultivar, maturity stage, and processing modality significantly influenced the chemical composition, presence of functional groups, and thermal stability of the hurd. Py-GC/Ms revealed substantial variations in the lignin-to-carbohydrate (L/C) ratio, along with the absence of fatty acids in certain cultivars. While FTIR signals confirmed consistent functional groups, differences in peak intensities were indicative of carbohydrate variations associated with maturity and retting duration, impacting the availability of hydroxyl groups for, i.e., interparticle bonding in citric acid-based bio-composites. Furthermore, it was observed that shorter retting durations initially enhanced the thermal resistance, but prolonged retting led to accelerated degradation, significantly reducing the hurd’s residual mass. The findings indicated notable differences among the samples, emphasizing the importance of investigating variables such as provenance/cultivar, maturity,andprocessing modality. This assessment is essential to ensure effective agronomic practices that align the raw material characteristics with the specific requirements of intended applications, such as the fabrication of biobased hemp hurd composites. © 2024 The Authors.

In the urban atmosphere of bengaluru, various volatile organic compounds(VOCs), particularly benzene,Toluene, Ethylbenzene, and Xylene(bTEX), have shown an increasing trend in concentration. The present research was conducted during summer and monsoon seasons, focusing on Kadubeesanahalli, a high-traffic area within the bengaluru Metropolitan City. Hourly sample data was collected using a bTEX analyzer(Model GC955-600) and subsequently transformed into daily, monthly, and seasonal values. The study revealed distinct patterns in benzene concentrations. benzene levels were lowest during the early morning hours, specifically from 1:00 *** 7:00 a.m.. Concentrations then increased from 7:00 a.m. to 9:00 a.m. and again from 4:00 p.m. to 11:00 p.m.,corresponding to the morning and evening peak traffic hours. However, between 10:00 a.m. and 4:00 p.m., the concentration decreased due to reduced traffic levels. These diurnal variations in benzene concentration are influenced by meteorological parameters. Comparing the two seasons, higher concentrations of benzene, Ethylbenzene, and MP-xylene were observed during the summer season. This increase is attributed to the elevated temperatures during summer, which promote the vaporization of bTEX compounds. Conversely, lower bTEX concentrations were recorded during the monsoon season due to the wet deposition process. The observed positive correlation(r > 0.5) among bTEX parameters strongly suggests a common source, most likely originating from vehicular emissions.
