This paper presents a model for the optimal design of reinforced rectangular concrete beams for singly reinforced sections. It develops an analytical approach to the problem, based on a criterion of minimum cost and minimum weight design... A Luévanos Rojas - 《Dyna》 被引量: 7发表: 2016年 ...
Later, about 3000bceinMesopotamia, the firstfiredbricks appeared. Ceramicpotteryhad been developing in these cultures for some time, and the techniques ofkiln-firing were applied to bricks, which were made of the same clay. Because of their cost in labor and fuel, fired bricks were used at ...

Contractors need to follow these specifications closely during preconstruction. Fire resistance requirements can have a significant impact on material costs, as well as material availability. If a contractor substitutes unapproved materials, whether for cost savings or ease of use, they could cause abre...
Precast concretecomponents include slabs, beams, stairways, modular boxes, and even kitchens and bathrooms complete with precast concrete fixtures. A prefabricated building component that is mass-produced in anassembly linecan be made in a shorter time for lower cost than a similar element fabricated...
Building container-based structures off site just makes sense. We’re assembling buildings in 40% of the time traditional construction would take, and at a lower cost. I can very clearly see a future where container-based building is on the table for every structure.” ...
1. Cost: The budget allocated for a project strongly impacts the selection of construction and building materials. 2. Durability: Materials with long lifespans are preferred to ensure the longevity of the structure. 3. Sustainability: Choosing eco-friendly materials reduces the environmental impact of...
However, sensors are only installed in parts of the structure. This is because the sensor layout must not impact the original structural properties of the building. Moreover, installing many sensors isn’t cost effective. As a result, we have to place as few sensors as possible, while...
However, since building carbon emission information and building cost information are highly similar in content and structure, the self-defined carbon emission information entity can be constructed by referring to the items of the cost information entity IFCCost prefix. Its self-defined carbon emission...
