(5)In accordance with the design drawings for reinforcing steel (-16 × 150 material Q345B) production
(9)Fill concrete hole, fill node empty hole with composite filling material, then support mold, sealing and filling, then to enhance moisture conservation.
From the perspective of the force ,we found that reinforcement mechanism clear and structure simple , the force of node C is more reasonable, which can improve the seismic capacity of structures; From the view of construction, this program can be used to avoid sinking concrete at node C, has industrial production of the material on C reinforcement nodes and has little interference on the normal building construction, which can achieve ecological construction, greatly improve the efficiency of the construction and meet the schedule demands; From the view of the function, C node has an impact on the appearance of the original structure, however, after renovation, it can still meet the requirements.

But in the "eleven five" National Science and technology support project "modern architectural design and construction of key technology research", the research of BIM technology clearly, and to build and conforms to the BIM Standard Specification in our country based on international standards, the development of key BIM in the "Twelfth Five Year" during the construction of informationization, construction of digital city the overall goal of architecture and technology development, the development of BIM technology is the necessary way to achieve this goal.
This value only for the operation of building energy consumption, not including building materials manufacturing and construction process energy consumption.
Because the sunlight analysis does not involve property of building material, is simply analyzed according to the geometry.

Research on the stiffness of concrete filled steel tubular column and steel beam joint with stiffening ring Li Jian Architecture and Civil Engineering School Inner Mongolia University of Science and Technology, Baotou, China ljwqy@163.com Keywords: joint; stiffness; stiffening ring; plastic hinge Abstract.
Throughout these 10 years of research, many scholars beam - column joint, departure from “Structure is simple and clear, transfer, material savings and convenient construction”, node in the form used for the specific project, and to explore new forms node[1-3].Node computational model to determine the most people as completely rigid connection or ideal articulated two types.
initial 3.1.2 Nodes are connected detail size If you do not consider the material factors, the node connection detail size is mainly determined by the width and thickness of the strengthening ring.

Experimental materials and methods Experimental water samples.Source of the ceramic printing wastewater: Jiatai printing plant of Chaozhou in Guangdong Province pH: 6.66 CODCr: 8220 mg/L Suspended Solids Concentration: 0.134 mg/L Chroma: 1000 times Turbidity: 1640 NTU .
Under alkaline conditions, the suspended solids removal has not risen, but declined, possibly the main ingredient of the ceramic wastewater is silicate material, first the pH is lower, gradually, after alkaline of the solution, appear H2SiO42-, Because most silicates are not dissolved, so, with the increase in suspended solids, suspended solids removal efficiency decreased.
