60 A practical approach to the optimal design of precast, prestressed concrete highway bridge girder systems is presented. The approach aims at standardizing the optimal design of bridge systems, as opposed to standardizing girder sections. Structural system optimization is shown to be more relevant than conventional girder optimization for an arbitrarily chosen structural system. Bridge system...

In order to manage site precast concrete construction which has been increasing, an integrated construction management system employing a unique 3-D modelling method and analogue process input method was developed. At the planning stage, the system supports interactive planning between member configuration and installation planning by a visual method and with an accurate quantity. At the proces...

Productivity estimation is a crucial task for construction managers and general estimators to efficiently allocate the required resources in order to minimize the construction costs. There is a lack of research in terms of productivity modeling for precast erection process. Therefore, this study was designed to develop a model based on Artificial Neural Networks (ANN) to predict the installatio...

With the growing worldwide attention towards environmental protection, rational utilization of rice straw (RS) has gradually attracted scholars. This paper innovatively puts forward a solution for RS. A fiber concrete (RSFC) with good physical and mechanical properties concrete-light steel keel wall panel (RS-LSWP) low comprehensive heat transfer coefficient inconspicuous cold bridge phenomenon...
