Paper Abstract
The composite steel shear wall (CSSW) consists of a steel shear wall (SSW) attached to a reinforced concrete panel using bolts or connectors. In this way, thick-walled steel plates exhibit a higher load-carrying capacity and are less likely to buckle out of the plane. This paper develops a new analytical strip model for 3, 8 and 15 floors frames equipped with CSSW as well as traditional steel shear walls (SSWs) to investigate their seismic behavior. The results of conducted pushover analyses showed that more plastic hinges were created in the CSSW-equipped frames than SSW-equipped ones, indicating more energy absorption, fewer damages and more durability.
- The seismic behavior of 3, 8 and 15-floor frames equipped with composite steel shear walls (CSSW) and conventional steel shear walls (SSW) was analyzed by pushover analysis.
- To this end, triangular template lateral loading was applied to the numerical models, and the plastic hinges of beams, columns and diagonal steel strips were obtained.
- The diagonal steel strips went to the plastic region before the surrounding beams and columns in all numerical models.

Paper Abstract
The use of industrial waste as a building material plays an important role in sustainability. During the combustion of pulverized coal, fly ash is generated as a waste product. An overview of research on the use of sintered fly ash aggregate for the production of light-weight structural concrete is presented here. In this paper, the aggregate properties of fly ash are also determined by the physical, chemical, and pelletizing parameters of the flash. This paper also discussed temperatures and durations of sintering and their significance. A description of the sintered fly ash aggregate's mechanical and physical properties was also provided. Literature review indicates that such aggregates are 16–46% lighter and have a higher water absorption capacity than normal-weight aggregates. The concrete produced with sintered fly ash concrete exhibited high strength and mechanical properties as well as durability.. The compressive strengths of sintered fly ash aggregate concrete range from 27-74 MPa, and the densities range from 1651-2017 kg/m3. Fly ash aggregate concrete seems to perform well in terms of structural applications. Sintered fly ash aggregate concrete has been identified as potential structural concrete material.
- Fly ash for construction cannot be generated, characterized, or used without understanding how it is produced.
- In addition, fly ash is diverted from landfills, reducing the need for OPC. A cleaner production process can also be achieved by reducing air pollution, emissions, and solid waste.
- The physical, chemical and mineralogical characteristics of fly ash make it an inherently complex material. The combustion temperature, cooling rate, and composition of fly ash all influence its physical and cementitious properties.
