Appropriate production plans can make resources utilized effectively as well as minimize waste. However, currently most of the precast fabricators propose production plans depending on the rule of thumb, resulting in the squander of resources and postponed delivery. Computerized scheduling techniques provide more precise outcomes than those made manually. The goal of this study is to develop a ...

We outline a new approach to process modeling in support of development of product data models. It is based on the definition of process models with far greater detail than have been used previously, and on the automated mapping of these models to product model schemas. A new process-modeling tool was developed for this purpose along with applications for structuring and analyzing the data coll...

This paper reports the results of three thin wythe precast sandwich panels tested under axial load. Panel reinforcements and shear connectors in current state civil construction context are evaluated. The authors measured displacement at two distinct panel heights as well along width to provide load–displacement behavior cross-section level broaden experimental data on subject. test developed t...

This paper compares the measured lateral load behaviors of two 0.4-scale “hybrid” precast concrete wall test specimens – one wall with solid panels and the other with perforated panels. The test specimens have the same overall geometry and utilize a combination of mild [i.e., Grade 400 (U.S. Grade 60)] steel and high-strength unbonded post-tensioning (PT) steel for lateral resistance across hor...

Abstract After pouring concrete precast cavity shell structure has been developing rapidly in recent years, compared with cast-in-place structure, the new fabricated low cost, high construction efficiency, and advantages of green environmental protection, shear wall is most widely used, which includes prefabricated plate shell, annular tendon layout, cast-in-situ important process. But by sever...

This study investigated the seismic performance of cementitious grout filled coupler and sleeve connections in precast wall panels under cyclic lateral loading. The effectiveness these enhancing concrete walls was evaluated. In many countries, grouted are preferred option, whereas were more commonly utilized India due to belief that a greater portion dowel being enhances structural stability. T...

Buildings are complex products containing relatively large numbers of distinct parts that are collected in multiple assemblies for different design, analysis and production purposes. Modeling buildings in fully parametric 3D CAD systems offers numerous benefits in terms of productivity, the ability to rapidly generate design alternatives at different levels, and elimination of errors that resul...

In recent years there has been an increasing tendency to recycle the wastes generated by building companies in the construction industry, demolition wastes being the most important in terms of volume. The aim of this work is to study the possibility of using recycled aggregates from construction and demolition wastes in the preparation of precast non-structural concretes. To that purpose, two d...
