The necessity and importance of studying the dynamical characteristics of ramp steering was described. After the force analysis of ramping going up, down and along the slope, Especially don‘t ignored unchanged load distribution that was caused by the longitudinal force and lateral force, Establish the mathematical model of traction and braking force. Through the simulation experiment, the result showed that the traction and braking force changed with definite rules when the tracked vehicle turned on the slope, which has practical significance for the further study of the vehicle’s power matching problems.

Purpose – This paper aims to explore the relationship between designed and actual building performance as represented in an Royal Institute of British Architects- and Chartered Institution of Building Services Engineers-backed web-based comparison platform and the industry perception of the pressures surrounding building performance assessment. European directives and UK Parliamentary Acts have resulted in a range of mechanisms aimed at encouraging monitoring of energy consumption, responsive management and evidence-based design. Web-based feedback platforms aim to feed evaluation data back to industry anonymously; however, there exists a range of barriers and disincentives that prevent widespread and habitual engagement with building evaluation. Design/methodology/approach – Using energy data from the CarbonBuzzweb platform and a series of semi-structured interviews, a mixed-methods study has been carried out. Analysis of the characteristics of the existing energy discrepancy between designed and actual performance shows where variance typically occurs. Interviews with industry actors presents a synopsis of the perceived and actual legislative and procedural pressures that exist in relation to building performance assessment. Findings – The conclusions of this paper identify weaknesses in the current legislative and incentivisation mechanisms with regard to targeting building energy performance and industrial pressures that hinder broader industry engagement with post-occupancy evaluation. Originality/value – The recommendations arising from this study are for adjustments to the existing legislative framework to increase participation in meaningful building energy evaluation targeted at the specifics of the energy gap and the motivations of industrial actors. This will specifically help to reduce building energy consumption and associated carbon emissions.

The FEMA P-807 guideline titled Seismic Evaluation and Retrofit of Multi-Unit Wood-Frame Buildings with Weak First Stories is a new approach for building retrofit. It goes beyond current building codes and standards by quantifying performance in probabilistic terms. The authors performed an independent review of P-807, and the resulting commentary herein covers five topics: (1) building lateral force-drift (backbone) curves, (2) building interstory drift limits, (3) lateral strength requirements, (4) collapse safety margins, and (5) site class effects. It was concluded that P-807 may be an efficient way for relative ranking and selection of retrofit designs—but it has questionable accuracy for predicting actual building performance (i.e., the probability that a particular seismic intensity will result in a meaningful state of damage for a specific building).
