The suitability of precast concrete walls containing recycled aggregates as the enclosure system of steel structure was investigated. The experiment on steel frame with external hanging concrete walls containing recycled aggregates (SFECW) was carried out under horizontal low-cyclic loading, and the influence of beam-column joints forms on the SFECW was considered. The failure modes, structural capacity, lateral stiffness, ductility and energy dissipation capacity were analyzed. The experimental results show that the external walls can remarkably increase the structural capacity, stiffness and energy dissipation capacity, and the connecting stiffness of beam-column joints has negligible effect. There were obvious buckling deformation of the steel column base and serious cracking and damage of the wall at the hanging points, and the corresponding suggested improvements were proposed. Furthermore, the load-displacement curves and failure modes of the SFECW were investigated by the finite element method, and the influence of key parameters such as the position of hanging points, the strength grade of recycled concrete, the thickness of wall, the height-span ratio and axial compression ratio on the SFECW were discussed. The FEA results indicate that the design parameters associated with the external wall are less affected to hysteresis performance of the SFECW, which provides scientific basis for the design and practical application of the SFECW.

The emergency information released in map is necessary for emergency management and disaster reduction. We present a new method for emergency map symbols extraction from symbol collection based semantic representation in this paper. A novel map symbol semantic matrix is introduced to measure the degree of the semantic representation between the symbol meaning and the emergency event conception. The necessary content factors of emergency for releasing in map are conduced by analyzing the emergency content construction and statistic result of the emergency content published by national disaster reduction center. The fuzzy comprehensive evaluation is proposed to extract the map symbol class. The sub function f i (k i ) is designed to confirm the grade of ith evaluation factor(ki) in event extent. By analyzing the example, the effectiveness and practice of this present method are proved.

This thesis is concerned with the efforts to develop a general-purpose systems engineering model software TRPSEMPro1 that can be used to improve productivity in the design process. Different features of TRPSEMPro will be presented in this thesis. First, Systems Engineering technology is presented, followed by the exposition of different numerical optimization technologies and DOE (Design of Experiments) study technologies. Second, the detailed software process, Object-Oriented Analysis and Design (OOA&D) for the TRPSEMPro is presented. All the design data models are expressed by using Unified Modeling Language (UML). AMUSESimulator is another software package which has been designed and implemented in order to serve as a bridge between AMUSE Macro, developed by ANL, and systems engineering model, TRPSEMPro. The design process for AMUSESimulator is elaborated in this thesis. The topics in this thesis also include SQL Server Database, XML, DOE techniques and optimization techniques. Several study cases which apply the developed systems engineering model to solve typical design problems are demonstrated.
