Based on the experiment of four models of reduced scale high-rise reinforced concrete wall under low-reversed cyclic loading, seismic behavior of reinforced concrete (RC) shear wall with diagonal web reinforcement under different ratio of axial compression is studied, in comparison to ordinary shear wall. The experiment result shows that diagonal bars affect the distribution of cracks and help to resist shear slip at the bottom of the wall. Seismic behavior of high-rise shear wall, which horizontal bars are replaced with the same amount diagonal bars in part can be obviously improved when the ratio of axial compression is high, but when the ratio of axial compression is low, the effect is not obvious.

Purpose – The purpose of this paper is to present a systematic approach for the evaluation and selection of curtain wall systems for medium-high rise building construction. Design/methodology/approach – The authors have identified the different types of curtain wall systems that are commonly used in the building construction industry in Saudi Arabia; examined the various performance as well as financial and non-financial criteria affecting the evaluation and selection of these systems; and subjected the identified different types of curtain wall systems to several filtering processes, namely feasibility ranking, evaluation by comparison and weighted evaluation to facilitate making a decision on the most suitable system to select. Findings – The analysis of the collected data indicated that the precast concrete curtain wall system is considered to be the first choice. The second choice is the prefabricated brick panel curtain wall system. Originality/value – Curtain walls are the most recognized elements of contemporary structures today. There exists ample variety of materials and designs that could be utilized for the development of these building elements. This paper is of practical value to project owners, architects and design professionals endeavoring on the process of selecting and specifying curtain wall systems in their projects.

Mechanics Characteristics

The high-rise concrete residential market has been a gradually urban mainstream in recent years, and frame-shear wall structure is more used for high-rise residential structures now. This kind of structure has the advantage that the combination of frame and shear wall make the space free and flexible, and therefore the whole structure has considerable rigidity. The structure can not only satisfy the needs for people living in comfortable, but also has good dynamic and static load bearing capacity. This paper analyzed the mechanics characteristics of the structure and summarized the two kinds of main failure modes of shear wall and frame structure in earthquake. On this basis, the main principles are put forward to improve the seismic behavior of the shear wall. And further some of specific measures and suggestions which can improve the seismic performance for the frame-shear structure are introduced.

New Form

BIPV is now widely used in office and residential buildings, but its seismic performance still remained vague especially when the photovoltaic (PV) modules are installed on high-rise building facades. A new form of reinforced concrete shear wall integrated with photovoltaic module is proposed in this paper, aiming to apply PV module to the facades of high-rise buildings. In this new form, the PV module is integrated with the reinforced concrete wall by U-shaped steel connectors through embedded steel plates. The lateral cyclic loading test is executed to investigate the seismic behavior and the electric and thermal performance with different drift angles. The seismic behavior, including failure pattern, lateral force-top displacement relationship, and deformation capacity, was investigated. The power generation and temperature variation on the back of the PV module and both sides of the shear wall were also tested. Two main results are demonstrated through the experiment: (1) the U-shaped steel connectors provide enough deformation capacity for the compatibility of the PV module to the shear wall during the whole cyclic test; (2) the electricity generation capacity is effective and stable during this seismic simulation test.

Wall Element

In this paper, the object-oriented method is used to study the pre-processing system of 3D high-rise building steel structure CAD. For the high-rise building steel structure design optimization system, users mainly contact with the functions of modeling, analysis, design checking and drawing. In fact, all these functions are carried out around the data stored behind. Three-dimensional high-rise building steel structure CAD pre-processing subsystem mainly integrates three-dimensional entity construction module, node design and editing module, construction drawing, processing drawing and CNC data output module. In this paper, the wall element is used to simulate the shear wall element, and the wall element can be automatically refined into a shell element composed of quadrilateral membrane element with rotational degree of freedom and generalized conforming bending plate element for thick and thin plate, which improves the speed and accuracy of analysis and calculation of shear wall. Various loads of high-rise building are calculated, especially the wind load of space action. It provides a new idea for wind load calculation of high-rise buildings. It is better to put forward a practical system optimization model, which can deal with the objective function, variables and constraints in a large number of engineering processing, and consider the actual constraints as fully as possible, which has strong practicability.
