Formation Design

The sandwich external wall panel is made of fireproof Paper Honeycomb Board (PHB) as kernel material, and the external surface is covered by colorful extruded steel board, while the internal surface is coated with the thermal insulating frothing ceramic board or the calcium silicate board, which works as the insulating layer or protecting layer of the panel. Two types of formation design are suggested, i.e., Type-A and Type-B. After corresponding thermal calculation, the maximum thermal transmission factor is determined as 0.424W/(m2• K), which complies with the threshold stipulated in the National Code for external wall panel used in cold climate area. The newly designed wall panel will save 65% of energy when compared with the traditional one made in 1980.

An external wall panel (EWP) as a novel alternative to provide spatial flexibility and improve the performance of external walls was developed. The purpose of this study was to analyze the thermal performance of this EWP. A simulation analysis was carried out to scrutinize whether it was vulnerable to condensation, considering South Korea’s weather conditions, and find countermeasures to prevent this. Results indicated that the indoor surface temperature with the measures of added insulation materials and an inserted thermal-breaker was over 16.5 °C and that these methods could prevent condensation. In addition, this study assessed unsteady-state thermal characteristics, linear thermal transmittance, and the effective thermal transmittance of EWP. Effective thermal transmittance was estimated in consideration of the heat transmittance of EWP and the linear thermal transmittance of its slabs and its connection parts. The thermal characteristics of the building envelope are needed to analyze effective thermal transmittance and linear thermal transmittance-associated thermal bridges.

Taking a building under construction as an example, based on ABAQUS software, studies the failure mode, hysteretic curve, displacement ductility and energy consumption capacity of ALC external wall panel under three working conditions of assembled stiffened column frame brace system, assembled frame system and cast-in-place frame system.The simulation results show that:1.Under the action of low cycle load, the assembled stiffened column frame support system has no damage,the maximum stress value is 6.98 MPa, which is located at the position of steel plate at the column bottom; 2.Under the condition of ALC hanging wall plate, the structure ductility is better; 3.Part of the energy consumption is borne by the light material hanging wall plate, and the stiffened column frame support system has higher energy consumption capacity.The assembled ALC external wall panel based on the rigid column frame support system has better mechanical performance, can significantly improve the energy consumption capacity of the overall structure, and has high construction feasibility,economy and engineering application value.

The article describes the design of buildings for multi-apartment houses 139 series, designed for construction in the conditions of the Kabardino-Balkaria Republic (KBR). An analysis of existing wall panel variants based on their thermal characteristics was carried out and a new constructive solution was proposed using porous fillers of KBR. The coefficient of thermal conductivity of the proposed structural concrete is determined analytically and the heat engineering calculation of the external wall panel is presented.

The lateral performance of a typical reinforced concrete external wall panel is analyzed by finite element method and the analysis results show that the reinforced concrete external wall panel has a certain strength and stiffness in its own plane. In order to rational use the strength and stiffness of the wall panel, a new type of energy dissipation connector is designed based on passive energy dissipation. The energy dissipation connector is analyzed by finite element method and the analysis results show that this energy dissipation connector has ideal hysteresis curve. The energy dissipation connector can improve the seismic behavior of main structure through rational design.
