Study on the Stress Performance of an Incompletely Prefabricated Profile Steel Reactive Powder Concrete Column in High-Rise Modular Buildings
نویسندگان
چکیده
In this study, 11 PSRPC column specimens were designed and fabricated in order to investigate the stressing performance of incompletely prefabricated steel reactive powder concrete (PSRPC) columns subjected static loading tests. The effects strength grade content (RPC) on axial compression eccentricity investigated. test results show that external RPC, internal section cast-in-place RPC work well together. damage morphology load–displacement strain relationships analysed, mechanism main factors influencing compressive load capacity are compared with calculation Chinese code (JGJ 138-2016) European American codes (AISC-LRFD), applicability existing is discussed. Based hoop restraint action limit state design method, formulae for calculating partial established. calculated values good agreement values, errors within 10%.

چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
15 صفحه اولCOST ESTIMATION OF HIGH PERFORMANCE CONCRETE (HPC) HIGH- RISE COMMERCIAL BUILDINGS BY NEURAL NETWORKS High-rise commercial buildings
Neural network approach is applied to establish relationships between the quantities/cost of the concrete/formwork, which is required for the structural elements of tall buildings using high performance concrete (HPC), and the design variables. Hybrid and hierarchical strategies are proposed for the cost estimation, where the feed-forward networks are adopted. After training, the neural network...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
CRITICAL INCIDENT ANGLE FOR THE MINIMUM COST DESIGN OF LOW, MID AND HIGH-RISE STEEL AND REINFORCED CONCRETE-COMPOSITE BUILDINGS
One of the main tasks of engineers is to design structural systems light and economic as possible, yet resistant enough to withstand all possible loads arising during their service life and to absorb the induced seismic energy in a controlled and predictable fashion. The traditional trial-and-error design approach is not capable to determine an economical design satisfying also the code require...
متن کاملA Macro-element Based Practical Model for Seismic Analysis of Steel-Concrete Composite High-Rise Buildings
Seismic behaviour of steel-concrete composite high-rise buildings, composed of external steel frames (SF) and internal concrete tube (CT), with rectangular plan is investigated in this paper. A macro-element based model is established for seismic analysis of composite high-rise buildings aiming at predicting their global responses under earthquakes. By employing this macro-element based model, ...
