A Simplified Model for Modular Green Roof Hydrologic Analyses and Design
Green roofs can mitigate urban rooftop stormwater runoff. However, the lack of accurate, physically-based performance assessment and design models has hindered their wide application. Most hydrologic or hydraulic models have no direct connection to the physical properties of green roof components such as media type/depth, drainage depth, etc. In an effort to assist design engineers, a simplifie...
متن کاملQuantifying Evapotranspiration from a Green Roof Analytically
Green roofs are a common stormwater control measure used to help mitigate increased stormwater runoff caused by urbanization. Green roofs can retain upwards of 90% of rain given the appropriate conditions. Green roof design parameters, such as substrate composition and depth and plant type, affect the retention capabilities of green roofs by storing and allowing greater extraction of water by p...
متن کاملA generic hydrological model for a green roof drainage layer.
A rainfall simulator of length 5 m and width 1 m was used to supply constant intensity and largely spatially uniform water inflow events to 100 different configurations of commercially available green roof drainage layer and protection mat. The runoff from each inflow event was collected and sampled at one-second intervals. Time-series runoff responses were subsequently produced for each of the...
متن کاملPaViz: A Power-Adaptive Framework for Optimizing Visualization Performance
Power consumption is widely regarded as one of the biggest challenges to reaching the next generation of high-performance computing. One strategy for achieving an exaflop given limited power is hardware overprovisioning. In this model, the theoretical peak power usage of the system is greater than the maximum allowable power usage, and a central manager keeps the aggregate power usage at the ma...

چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
